摘要
探讨了天然膨润土对Pb2 +的吸附性能及其主要影响因素 .天然膨润土对Pb2 +的吸附能力很强 ,当Pb2 +的浓度小于 2 0mg/L时 ,去除率可达 99%以上 .吸附受溶液 pH、吸附剂用量以及振荡时间的影响 ,但溶液中存在的有机污染物不影响膨润土对Pb2 +的吸附 .
Adsorption of Pb 2+ on Bentonite and major affecting factors were studied.The results showed that when the concentration of Pb 2+ was less than 50?mg/L, the natural Bentonite adsorbed Pb 2+ effectively with the moving rate more than 99%. pH value amount of adsorbent, time of reaction and intensity of ion effected the adsorption, but p\|nitrophenol in solution did not affect the adsorption.
