【Abstract】 The biosorption of Cu 2+ to brown algae was studied by the catalytic kinetic spectrophotometry.Several parameters,such as the amount of the brown algae,chemical pretreatment of the sorbent,adsorption time,and pH value were examined in detail.The results showed that a effective biosorption of Cu 2+ on brown algae was achieved at pH 3 6 after pretreatment of the algae with 0 05% NaOH.The biosorption equilibrium was reached within 8 min with the adsorption capacity of 13 26 mg·g -1 .更多还原
