Effect of Temperature on Dissolution of Allophane with Alkaline Solution

Abstract

The previous experiments result showed that during dissolution process structure of KyP is more vulnerable to attack as compared to the structure of KnP. This features show that the type of dissolution of allophane is significantly affected by Si/Al ratio. The present experiment examines the dissolution rate of allophane at temperatures of 20 30 and 35C. The activation energy Ea will be determined to know stability of structure of allophane during dissolution process occurred.
