摘要
以蒙脱土为原料,经1mol/L盐酸改性处理后将其用于废水中铜离子的吸附,研究了吸附时间、pH值、土用量和铜离子初始浓度对铜离子吸附率的影响。结果表明:当铜离子浓度为10mg/L,溶液体积为50mL,pH值为6,蒙脱土用量为0.4g,吸附时间为1 h时铜离子的吸附率可达到91.48%。
Adsorption of copper ions on lmol/L hydrochloric acid modified montmorillonites was studied. The effect of the adsorption time, pH value, the amount of montmorillonite and the initial concentration of copper ions on the copper ions adsorption rate were studied.The results showed that when the concentration of copper ions is 10 mg/L, solution volume is 50 mL, pH value is 6, dosage of montmorillonite is 0.4 g, copper ions adsorption rate reached 91.48% in 1 h.
