Abstract

The preparation of bentonite–zeolite (BZ) adsorbent using bentonite, aluminate, and rice husk was conducted. The adsorption experiment was performed for the removal of Cu²⁺ and Zn²⁺ from aqueous solution in single and binary systems. Results showed that gasification of rice husk could effectively improve the specific surface area and pore volume. The optimum pH for Cu²⁺ and Zn²⁺ adsorption on BZ was pH 5.0. The pseudo-first order kinetic and Langmuir isotherm model of BZ were the optimal model for Cu²⁺ and Zn²⁺. According to Langmuir isotherm model, the maximum adsorption capacity value (q_m) was 16.39 and 12.72 mg·g⁻¹ for Cu²⁺ and Zn²⁺, respectively. The adsorption affinity order of BZ in the binary solution was Cu²⁺ > Zn²⁺. NH₄⁺-N concentration over 500 mg·L⁻¹ significantly affected the adsorption capacity of BZ (P < 0.05). The adsorption capacity of BZ for Cu²⁺ and Zn²⁺ was higher than that artificial zeolite (AZ) and bentonite in SW.
