This study sought to enhance the metal adsorption capacity of bentonite by improving its surfaces. Surface modification by the cationic surfactant (Bencylhexadecyldimethyl ammonium chloride, BCDMACl) was successful in this respect, and was characterized by FTIR spectroscopy, XRF, BET, and swelling test. A major characteristic of BCDMACl is forming micelles that can intercalate into interlayers of clay and prevent swelling. The adsorption of Cu (II) and Zn (II) from aqueous solutions was studied in batch experiments, varying both contact time and concentrations of the metal ions. Retention of the metals in solution was detected by Atomic Absorption Spectroscopy (AAS). The adsorption data were fitted with Langmuir, Freundlich, and Dubinin-Radushkevich isotherm models, of which the Langmuir isotherm provided the best fit with exptl. data (R2 range 0.962-0.993). The results also revealed that the modified bentonite had significantly improved adsorption capacities (qmax 50.76 and 35.21mg/g for Cu(II) and Zn(II), resp.); about 2.5 and 2.0 fold improvements over natural bentonite. The pseudo-second-order rate equation provided the best fit to observed adsorption kinetics. This study demonstrated the modified bentonite as an effective adsorbent for the removal of heavy metals from aqueous solutions This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Reference of 122-18-9).
N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Reference of 122-18-9
