| 中文摘要: |
| Exchange additivity of binary mixtures of hydrous metal oxides and clay minerals has been studied by investigating the relations of the zinc exchange-pH and the zinc partition coefficients to mixtures. The additive exchange equation is proposed to describe the exchange-pH relationship. The results suggest that zinc exchanges on the components in amorphous iron oxide/montmorrillonite, kaolinite/montmorrillonite, γ-Al00H/montmorrillonite, amorphous iron oxide/illite mixtures are additive. But the exchange of δ-MnO2/montmorrillonite is much less than its additive exchange. It is also shown that in the case of additive exchange the exchange parameters (Kmix{→SOH}Tmix) of the mixtures are equal in weight to the sum of those of each component of the solid mixtures. |
