Abstract: In order to explore the adsorption characteristics, liquid pH, and electrical conductivity variation characteristics of bupleurum dreg to the waste water containing zinc, the bupleurum dreg was utilized as biosorbent to remove Zn²⁺ with batch experiments. The effect factors on biosorption were analyzed, which included pH values, initial Zn²⁺ concentration (C₀), biosorbent concentration (ρ_m), and mesh size (M_z). Meanwhile, the isotherm biosorption and kinetics was analyzed. The results showed that the optimum condition for biosorption was as follows: pH was 4.5~6.0, ρ_m was 4.0~8.0 g/L, C₀ was 0.1~2.0mmol/L, M_z was 40~100 mesh. The isotherm adsorption curve of Zn²⁺ on bupleurum dreg accorded well with Langmuir and Freunlich model, and the R² value was 0.978 and 0.989 while the value of q_max was 19.96 mg/g. This shows that a bupleurum dreg has excellent adsorption capacity to zinc ions. The kinetics analysis showed that the biosorption of Zn²⁺ on bupleurum dreg was a rapid process, and the R² values were all above 0.997. These indicated that its limit step was chemical adsorption process. The variation trend of pH values in liquid was increasing rapidly at initial adsorption phase and then changed slowly in the succedent phases.
