Adsorption behaviors of modified clays prepared with structurally different surfactants for anionic dyes removal

In this study, the properties and adsorption behaviors of organoclays synthesized with two structurally different surfactants having same carbon chain length (hexadecyltrimethylammonium bromide (HDTMAB) benzyldimethylhexadecylammonium chloride (BDHAC)) were evaluated. The structural examined using Fourier-transform infrared spectroscopy, zeta potential analysis, X-ray diffraction, N2 adsorption-desorption test. modified clays increased surfactant loadings (from 0.5 CEC to 3 CEC) prepared find optimal loading. As a result, 1.5 cation exchange capacity (CEC) was found be organoclay HDTMAB (H-Bt) exhibited maximum 114.3 mg/g for anionic Orange G dye, which 1.74 times higher than that BDHAC (B-Bt). Furthermore, in presence mixture cationic dye molecules water, H-Bt tended remove more target compound B-Bt (i.e., methylene blue (MB)), suggesting can serve as efficient adsorbent uptake environmental contaminants practical scenarios. Moreover, study effects on their molecules.
