IR spectra of Cu (Ⅱ)-marine solid particle systems show that Cu (Ⅱ)-marine solid particle ion exchange causes a stepwise change in the surface H-bonding hydroxyl groups on illite . montmorillonite, CaCO3,r. AlOOH and goethite, but that this does not affect the surface free hydroxyl groups on illite. montmorillonite and CaCO3. and framework hydroxyl group on goethite and on γ- AlOOH . Over the range of Cu(Ⅱ) exchange amounts in the present experiment, four stepwise changes were discovered for the surface H- bonding hydroxyl group on illite. while two stepwise changes were observed on the other marine solids. The interfacial stepwise ion exchange theory was first demonstrated by the above experimental evidence .
