砷对离子交换法吸附硫酸锌溶液中氯离子的影响

Effects of Arsenic on Ion Exchange Adsorption of Chloride Ion in the Zinc Sulfate Solution

对某企业提供的含Cl-1.55 g/L、含砷2.24 g/L、含Zn2+145 g/L的硫酸锌溶液,采用大孔阴离子交换树脂吸附Cl-。结果表明,达到稳定平衡后,离子交换树脂对Cl-的吸附容量为21.2 mg/g,与无砷硫酸锌溶液比较,对Cl-的吸附容量下降19%。

Using the macroporous anion exchange resin adsorbed Cl-from some company’s zinc sulfate solution, containing Cl-1.55 g/L, As3-2.24 g/L and Zn2＋145 g/L.The results showed that the adsorption capacity of ion exchange resin of Cl-fell 19%, and its value was 21.2 mg/g, compared with the arsenic-free zinc sulfate solution, when stable equilibrium was reached.
