摘要 对比Pb2+,SDBS,PNP单元和三元复合后在煅烧高岭土上的吸附,探讨了在不同投加量、吸附时间、pH值下三元共存在煅烧高岭土上的吸附影响.结果表明:Pb2+单元去除率为94.71%,三元复合后为85.50%;SDBS单元去除率为75.36%,三元复合去除率为84.04%;PNP单元去除率和三元复合去除率分别为64.24%,55.57%.表明三元复合对Pb2+和SDBS的去除产生拮抗效应,而三元复合对PNP起到增强吸附的作用.由IR红外分析可知煅烧高岭土吸附三元复合污染物并没有引起结构的改变,吸附过程为物理吸附. Based on the comparative analysis of the adsorption on unit and ternary complex ofPb2+ SDBS, PNP by calcined kaolin, we explored the adsorption impact on the calcined kaolin in the different dosage, adsorption time, and pH values. The results show that the removal rate of Pb2+in the unit system and the ternary complex system is 85.50% and 94.71% respec tively. The removal rate of SDBS in the unit system and the ternary complex system is 75.36% and 84.04% respectively. The removal rate of PNP in the unit system and the ternary complex system is 64.24% and 55.57% respectively. It proves that there is an antagonistic effect on Pb2+ and SDBS after ternary complex; meanwhile, a promote adsorption effect on PNP after temary complex. Besides, IR infrared analysis shows that adsorption pollutants of kaolin do not cause changes in the structure of the kaolin. And the adsorption process is physical adsorption.
