Effect of coexisting ions on Cr(VI) adsorption onto surfactant modified Auricularia auricula spent substrate in aqueous solution.

In this paper, the effect of coexisting cations and anions on Cr(VI)(in the form of CrO) adsorption onto Auricularia auricula spent substrate (AASS) modified by cetyl trimethyl ammonium bromide (CTAB) was investigated in batch adsorption experiment. The Cr(VI) adsorption capacity of 9.327 mg/g, obtained at pH 3.
