We studied the removal of K-2BP from aqueous solution by cetyltrimethylammonium chloride-modified bentonite with polyacrylamide flocculant (CTAC-bentonite/PAM). The preliminary results disclose that the CTAC modification method can potentially enhance the removal efficency of bentonite and, by combination with PAM, the adsorbed bentonite can settle within a short sedimentation time. In addition, alkaline condition is favorable for the adsorption; however, temperature influence is weak. Considering the high efficiency and low cost, CTAC-bentonite/PAM could broadly extend in the treatments of dye wastewater.
