| Abstract: | The exchange action of six types of organic phenols on day surfaces in seawater is systematically studied in this work. The following significant conclusions are drawn from the experiments. (1) The interaction of organic phenols with montmorillonite, illite and kaolinite in seawater is monovalent anion exchange. (2) Their isotherms of stepwise exchange on day surfaces belong to the Langmuir type or step-wise type.(3) The discovery of the"steric hindrance effects of stepwise exchange of organic phenols on days surfaces", and revelation of an exchange mechanism different from that in references are the greatest achievements in this work. |
