| 摘 要： | 制备了高效SO4^2-吸附剂,用其对某煤矿矿井水进行了试验,对影响吸附剂吸附效率的各因素进行了研究,结果表明：吸附剂用量1.0 g/L时,去除率达到最高,为93.5%。溶液在酸性范围内吸附剂对SO42-去除率明显大于碱性范围。随着SO4^2-浓度的增加,吸附剂的去除率逐渐降低。试验水温选择为25℃,最佳吸附时间为40 m in,最佳pH为7.0。

| Abstract: | Prepared a high efficiency SO4^2- adsorption agent,tested in a coal-mine drainage with it,studied the factors affecting the adsorption efficiency of adsorption agent.As a result,the removal efficiency achieved 93.5% when the adsorption agent dosage is 1.0 g/L,the SO4^2- removal efficiency is higher in acidulous water than alkali water.The removal efficiency felled gradually with the SO4^2- concentration increasing.Adopted 25℃ as the tested temperature.The best adsorption time and pH is 40 min and 7.0 respectively. |
