| Outline of Final Research Achievements |
Experimental dissolution of kaolinite in solutions containing BSA and various amino acids including acidic, neutral, and basic amino acids were performed to evaluate the effect of organic molecules on dissolution of minerals in the earth's surface environments. Results indicated that the dissolution rate of kaolinite was enhanced by the interaction of BSA. Acidic amino acids also exhibited greater enhancement of dissolution rate relative to the neutral and basic amino acids. Therefore, the interactions between positive sites of kaolinite surface and negative sites of organic molecules would be play an important role as rate enhancement mechanism of this experiments.
