| 摘 要： | 进行了矿渣去除废水中铬、铅离子的试验研究，探讨了接触时间、金属离子初始浓度、废水酸度等因素对吸附性能的影响。结果表明，有较宽的ｐＨ范围内矿渣对铬、铅离子有较强的吸附能力，基本符合Ｆｒｅｕｎｄｌｉｃｈ吸附等温式，铅离子的吸附容量略大于价铬离子。

| Abstract: | Study on the removal of Cr3 and Pb2 from wastewater by blast-furnace slag has been conducted depending on contact time, initial ion concentration and pH of solution. The result showed that the slag has higher removal efficiency at a wide pH range for lead and chromium. The adsorption capacity of slag for Cr3 and Pb2 follows Freundlich isotherms in the range of the concentration studied. The adsorption capacity of Pb2 was found to be greater than of Cr~(3 ). |
