Title: Study on Absorption of Pb~(2+)/SDBS/PNP Ternary Coexistence Pollutants by Calcined Kaolin
Abstract: Based on the comparative analysis of the adsorption on unit and ternary complex of Pb2+,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% respectively. 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 ternary 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.
