Effective antimony removal from wastewaters using polymer modified sepiolite: Isotherm kinetic and thermodynamic analysis was written by Saleh, Tawfik A.;Tuzen, Mustafa;Sar, Ahmet. And the article was included in Chemical Engineering Research and Design in 2022.COA of Formula: C9H3Cl3O3 This article mentions the following:
Sepiolite was modified with polymer consisting of ethylenediamine(EDA)-trimesoyl chloride (TMC) to produce a highly effective sorbent for antimony (III) (Sb(III)) adsorption from aquatic solutions The EDA-TMC polymeric branches were grafted onto the surface of sepiolite by polymerization The surface morphol. and the main adsorptive chem. groups of the developed S/EDA-TMC sorbent were characterized by SEM, EDX, BET, and FTIR, anal. methods. The impact of the batch adsorption conditions on the adsorption performance was systematically studied by conducting a factorial design anal. While Langmuir and Freundlich isotherm models were employed with the non-linear equations to the removal data and the removal capacity of the prepared composite was estimated as 210.1 mg g-1 based on the Langmuir due to relatively high correlation. The kinetic investigation results displayed that the pseudo-second-order kinetic model was well appropriate for characterizing Sb(III) removal mechanism. Also, thermodn. findings verified that the Sb(III) removal onto the composite adsorbent progressed exothermically and spontaneously with temperature increasing from 24° to 55°C. Besides, the produced adsorbent demonstrated still appreciated adsorption/desorption yield (80/76%) after the 7th cycle. Accordingly, the fabricated S/EDA-TMC material can be evaluated as a powerful sorbent in the cleaning of aqueous solutions containing Sb(III) pollutants. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1COA of Formula: C9H3Cl3O3).
Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.COA of Formula: C9H3Cl3O3
