Abstract: 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 inter-action between montmorillonite molecule and [Cu(H2O)6]2+ or [Zn(H2O)6]2+ was possible. The exper-imental results of powder X-ray diffraction and isothermal adsorption supported the above-mentioned calculation results.
