摘要：
The frontier orbital energies of montmorillonite molecule and [Me(H2O)(6)](2+) (Me = Cu2+, Zn2+, Co2+ and Ni2+) were calculated by INDO method. Results showed that the chemical interaction between montmorillonite molecule and [CU(H2O)(6)](2+) or [Zn(H2O)(6)](2+) was possible. The experimental results of powder X-ray diffraction and isothermal adsorption supported the above-mentioned calculation results.
