The feasibility of utilizing CTAB–silica gelatin composite (C-SGC) to remove hexavalent chromium from aqueous solutions under different conditions was investigated. Removal of chromate was assessed through evaluation of the adsorption kinetics of chromate ions on the composite under equilibrium conditions in the presence of sulfate ions and at a slightly acidic pH condition (pH 5.8). Adsorption competition tests in the presence of sulfate ions showed that Cr(VI) was still effectively adsorbed from aqueous solution regardless of the presence of the competing anions. In fact, the adsorption kinetics performed at different initial chromate concentrations were unaffected by the presence of 100 mg L-1sulfate ions (pH 7.5). The equilibrium adsorption data were ﬁtted by Freundlich adsorption isotherms which conﬁrmed that the adsorption efﬁciency of chromium on the CTAB–silica gelatin composite was unchanged in the presence of sulfate ions. Further, the adsorption process was shown to be pH depen- dent and more efﬁcient at slightly acidic pH (5.8). These ﬁndings demonstrated a high speciﬁcity of the CTAB–silica gelatin composite for chromium, and highlight the possibility of using this matrix for efﬁ- cient removal of chromium from industrial wastewater without the need to eliminate contaminant sulfate ions.
