| 摘 要： | 用ICP—AES检测离子浓度方法研究了不同形态MnO2在不同pH下对污水中重金属离子Pb2+和Cd2+的吸附效果。结果表明:当溶液的pH=7时最有利于吸附,且α形态MnO2对重金属离子的吸附效果最好,其中对Pb2+最高吸附效率可达99.84%,对Cd2+的最高吸附效率可达71.54%。

| Abstract: | adsorption effect of the different forms of MnOz at different pH of sewage, heavy metal ions Pb2＋ and Cd2. ion concentration by ICP--AES method for study. The results showed that： the most conducive to adsorp on when the solution pH = 7, and the a form of MnOz on the heavy metal ions adsorption effect is best, which of Pb2＋ on the highest adsorption efficiency up to 99.84%, the highest adsorption eficiency of Cd2＋ up to 71.54%. |
