| Research Abstract |
To evaluate the effect of microbial organic moleclues on the dissolution rates of kaolinite, experiments on kaolinite dissolution in solutions with and without protein (BSA) were performed. Results of the experiments in near neutral solutions showed that the dissolution rates of kaolinite increased progressively up to 3.9 times with increasing BSA concentrations of 0.01, 0.02, 0.05, and 0.1 mg/ml. This results indicated that the dissolution rates of kaolinite were extensively enhanced by interaction of protein with the surface of kaolinite.
