| Research Abstract |
Experiment on dissolution of amorphous silica in solutions (pH4, 5, 6) 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 BSA greatly enhanced the dissolution rate of amorphous silica. Basic amino acids also exhibited stronger enhancement effect relative to neutral and acidic amino acids. Therefore, the interaction of basic amino acids residues with the amorphous silica surface are likely to play an important role as rate enhancement mechanism of BSA.
