| Abstract: |
| Determinded in this paper are 18 isotherms of Cu2+ and Pb2+ partitioning between liquid and solid (kaolinite, illite and montmorillonite), all proved to be "ion exchange-precipitation" isotherms. This is a new type of isotherms in marine chemistry. We have used the modified BET and Tóth equations to describe them. In this paper, we proposed the third expression, i. e. de Boer-Zwikker equation. Theoretically, this method has a proper chemical model. Practically, it is simple and easy to compare with experimental data. |
