英文摘要Difference of montmorillonite(Mt),illite(It) and kaolinite(Kt) in lead sorption characteristics and the effects of amorphous Fe and Al oxide coatings on the characteristics were experimentally sutdied with logistic model.The sorption curves had sigmoid feature due to use of acetate-type buffer solution.With the model the sorption process could be divided into four stages and the sorption characteristics at the stages were discussed.The results showed that,after Mt,It and Kt were coated by amorphous Fe oxide,their maximum sorption capacity(MSC) and percentage of high-SSC concentration scope(HCS) of Pb^2+ increased markedly,but the specific sorption capacity(SSC) decreased.with regard to effects of amorphous Al oxide coating,except for It+Al,the SSC of other samples showed a downtrend,despite that their MSC remained unchanged.Eventually,the gray correlation degrees to Pb^2+ sorption for different physicochemical characteristics of the clay minerals were indicated to be higher for hydronium,zero point of surface charge and hydroxy,but lower for specific surface area.density of surface charge and amount of surface charges.
