| 摘 要： | The interaction between minerals and heavy metals has been a hot object of study in environmental science,mineralogy and soil science,Through the selective adsorption experiment of Ca-montomorillonite,illite and kaolinite to Cu2 ,Pb^2 ,Zn^2 ,Cd^2 ,and Cr^3 ions at certain conditions,it could be concluded that Cr^3 is most effectively sorbed by all the three minerals.Also,it can be found that Pb^2 shows a strong affinity for illite and kaolinite while cu^2 for montmorillonite .Based on the adsorption experiment at varying pH of solution,it can be found that the amount of heavy etals sorbed by minerals increases with increasing pH of the solution.

| Abstract: | The interaction between minerals and heavy metals has been a hot object of study in environmental science, mineralogy and soil science. Through the selective adsorption experiment of Ca-montmorillonite, illite and kaolinite to Cu2+, Pb2+, Zn2+, Cd2+ and Cr3+ ions at certain conditions, it could be concluded that Cr3+ is most effectively sorbed by all the three minerals. Also, it can be found that Pb2+ shows a strong affinity for illite and kaolinite while Cu2+ for montmorillonite. Based on the adsorption experiment at varying pH of solution, it can be found that the amount of heavy metals sorbed by minerals increases with increasing pH of the solution. |
