In this study, a rapid, sensitive and novel nanodrop spectrometric approach is used for the trace level determination of cationic surfactant methyltrioctylammonium chloride (MTOAC) based on the reaction of Mo(III)-SCN^– complex with MTOAC in acidic condition. The molar absorptivity of red-colored Mo(III)-SCN^– complex was enhanced in the presence of MTOAC that is attributed to a hyperchromic shift. The absorptivity value of the complex with respect to MTOAC is 9.8 x 10⁴ L mol^-1 cm^-1 at λ_max 415 nm. The quality parameters show the good anal. performance of the proposed method with detection limit (LOD) of 8.3 x 10^-3 mg L^-1 and limit of quantitation of 2.7 x 10^-2 mg L^-1. The calibration curve for MTOAC determination obeys Beer’s law with the concentration limit of 0.05-0.40 mg L^-1 and determination coefficient (R²) 0.9992 along with slope and intercept 9.5 and 0.002, resp. The proposed NDS method has been applied successfully in different environmental and biol. samples for the determination of MTOAC.

Regulation of hexavalent chromium is based on Waste Framework Directive 1994/62/EC, European Commission and publication of the World Health Organization. Herein, detection of hexavalent chromium was performed by alk. digestion and instrumental anal. which was demonstrated in USEPA methods. However, UV-vis detection method could be affected by some metal ions reacted with diphenylcarbizide. Actually, various interfering elements, such as Ni, Fe, Al, and Cu, were detected and selected by ED-XRF in paper materials. In order to improve accuracy of anal. results of hexavalent chromium in paper materials based on USEPA methods, the interfering elements was removed by liquid-liquid extraction with carbonate media using tricaprylmethylammonium chloride and chloroform after alk. digestion. Consequently, the temperature for alk. digestion was between 85 and 95°C. Hydrochloric acid was proper complex tricaprylmethylammonium-Cr(VI) in the procedure of liquid extraction After that hexavalent chromium was completely extracted using of 1 M sodium hydroxide solution The technique for analyzing the hexavalent chromium used in liquid-liquid extraction significantly reduced the errors caused by the interfering elements, Fe and Cu. Thus, application of the extraction method was efficient in removing the interfering elements, which increased the recovery ratio of the hexavalent chromium from paper materials by 90%.

Industrial applications and environmental awareness recently prompted vanadium recovery spell from secondary resources. In this work, a polymer inclusion membrane containing trioctylmethylammonium chloride as carrier was successfully employed in electrodialysis for vanadium recovery from acidic sulfate solutions The permeability coefficient of V(V) increased from 0.29μm·s^-1 (without elec. field) to 4.10μm·s^-1 (with the 20 mA·cm^-2 c.d.). The transport performance of VO₂SO^–4, which was the predominant species containing V(V) in the acidic region (pH <3), was influenced by the aqueous pH value and sulfate concentration Under an elec. field, a low concentrated H₂SO₄ solution (0.2 M) effectively stripped V(V) from the membranes, avoiding the requirement of a highly concentrated H₂SO₄ without elec. field. Under the optimum conditions, the permeability coefficient and flux reached 6.80μm·s^-1 and 13.34μmol·m^-2·s^-1, resp. High selectivity was observed for the separation of V(V) and Mo(VI) from mixed solutions of Co (II), Ni (II), Mn (II), and Al (III). Addnl., the separation between Mo(VI) and V(V) was further improved by adjusting the acidity of the stripping solution The V(V) selectivity for the resulting membrane was higher than that of com. anion exchange membranes.

Enhanced removal of Cr(VI) by polymer inclusion membrane based on poly(vinylidene fluoride) and Aliquat 336 was written by Sellami, Ferhat;Kebiche-Senhadji, Ounissa;Marais, Stephane;Colasse, Laurent;Fatyeyeva, Kateryna. And the article was included in Separation and Purification Technology in 2020.Application In Synthesis of N-Methyl-N,N-dioctyloctan-1-aminium chloride The following contents are mentioned in the article:

New polymer inclusion membranes (PIMs) based on poly(vinylidene fluoride) (PVDF) (polymer matrix), tricaprylmethylammonium chloride (Aliquat 336) (ion carrier) and 2-nitrophenyloctylether (2NPOE) (plasticizer) were successfully elaborated by casting evaporation method and used in selectively facilitated transport of Cr(VI) ions in an acidic aqueous medium. Obtained PIMs are dense and homogeneous and are characterized by intermol. interactions of the membrane components (i.e. polymer matrix, ion carrier and plasticizer). The presence of ion carrier and plasticizer enhances the membrane flexibility and its hydrophilic character. The decrease of the PVDF m.p. is ascribed to the strong electrostatic interactions between liquid compounds (i.e. ion carrier and plasticizer) and polymer chains. PVDF-based PIM with only 20 wt% of Aliquat 336 ensures almost complete transport of Cr(VI) ions from the donor to acceptor phase. Moreover, the addition of 5 wt% of plasticizer significantly increases the transport flux. Also, Cr(VI) ions are selectively recovered (∼97%) from a mixture containing other heavy metal ions (Cd(II), Pb(II), Fe(III), Zn(II), Cu(II), Ni(II), Co(II)) with such PIM. Elaborated PVDF-based PIMs reveal improved transport properties compared to other polymer-based PIMs, exhibiting high stability (more than 190 h) and lifetime durability and so they are suitable for long term application. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Application In Synthesis of N-Methyl-N,N-dioctyloctan-1-aminium chloride).

Simple ammonium salts acting on sigma-1 receptors yield potential treatments for cancer and depression was written by Brimson, James M.;Akula, Kiran K.;Abbas, Haider;Ferry, David R.;Kulkarni, Shrinivas K.;Russell, Steven T.;Tisdale, Michael J.;Tencomnao, Tewin;Safrany, Stephen T.. And the article was included in Scientific Reports in 2020.SDS of cas: 5137-55-3 The following contents are mentioned in the article:

Sigma-1 and sigma-2 receptors are emerging therapeutic targets. We have identified that simple ammonium salts bind to these receptors and are effective in vivo. MTS assays were performed to determine their effect on growth in MCF7 and MDA-MB-486 cells. Anticancer properties were tested in NMRI mice transplanted with a fragment of mouse adenocarcinoma (MAC13). Antidepressant activity was tested using the forced-swim test and tail suspension tests. Dipentylammonium (K_i 43 nM), tripentylammonium (K_i 15 nM) and trihexylammonium (K_i 9 nM) showed high affinity for the sigma-1 receptor. Dioctanoylammonium had the highest affinity (K₅₀ 0.05 nM); this also showed the highest affinity for sigma-2 receptors (K_i 13 nM). Dipentylammonium was found to have antidepressant activity in vivo. Branched-chain ammonium salts showed lower affinity. Bis(2-ethylhexyl)ammonium (K₅₀ 29μM), triisopentylammonium (K₅₀ 196μM) and dioctanoylammonium showed a low Hill slope, and fitted a 2-site binding model for the sigma-1 receptor. We propose this two-site binding can be used to biochem. define a sigma-1 receptor antagonist. Bis(2-ethylhexyl)ammonium and triisopentylammonium were able to inhibit the growth of tumors in vivo. Cheap, simple ammonium salts act as sigma-1 receptor agonists and antagonists in vivo and require further investigation.

For a variety of reasons, such as high selectivity, easy control, easy reduction, and environmental compatibility, there is the high potential for the use of emulsion ionic liquid membranes (EILM) has been expanded. The edible oils have great potential for using in food industry extraction processes. Edible paraffin used for this purpose is less toxic and more cost-effective than other membranes. The technique of EILM based on edible oils was used as a chem. process for Pb²⁺ recovery from aqueous solution, using Aliquat 336 as an ionic liquid carrier and the ionic transport agent for Pb2+ ions in the membrane phase. The Tween 80 as a dispersive non-ionic surfactant was used for the emulsion formation. The kinetics and effective parameters on the membrane process performance were investigated. The results showed that factors such as the ratio of the internal phase to the organic phase, the concentration of ion carrier material, the surfactant concentration, and pH increasing had a pos. effect on metal separation efficiency. The maximum lead separation was performed for 3 and 10μL of Aliquat 336 and Tween 80, resp., in 20 mL of the organic phase. A removal percentage of 95% was achieved for 5 mg/L of lead in the feed phase. Using edible oil in this study was successfully developed to reduce the need for toxic organic solvents in preparing EILM for heavy metal solution treatment.

The aim of this research was to investigate ciprofloxacin (CIP) removal efficiency from aqueous solutions by using Fe₃O₄ nanoparticles @Trioctylmethylammonium thiosalicylat Ionic liquid (Fe₃O₄ NP@ TOMATS IL) as a new magnetic nanoadsorbent. The adsorbent was characterized by field emission scanning electron microscope-energy dispersive spectroscopy (FESEM-EDS), mapping, Fourier transform IR spectroscopy (FT-IR), the Brunauer-Emmett-Teller (BET), X-ray powder diffraction (XRD). The effects of solution pH, adsorbent dose, contact time, initial CIP concentration, and temperature on CIP removal were also investigated. In optimal conditions such as pH = 5.6, CIP concentration = 30 mg/L, adsorbent dose = 0.15 g, temperature = 30°C, contact time = 90 min, the removal efficiency in synthetic and real wastewater were obtained 87 and 73%, resp. Batch experiments were carried out to study the sorption Kinetics, thermodn., and equilibrium isotherms of CIP with magnetic nanoadsorbent. The results show that all of the above factors influence CIP removal. The Langmuir adsorption isotherm fits the adsorption process well, with the pseudo second-order model describing the adsorption kinetics accurately. The thermodn. parameters indicate that adsorption is mainly phys. adsorption. Recycling experiments revealed that the behavior of adsorbent is maintained after recycling for four times.
