Abstract
When the dissolution of allophane is promoted from the pore regions, the size of the pore regions become larger and this process is followed enlargement the pore of regions as network opening until the structure of allophane become collapse. The partial dissolution of allophane is very advantage for increasing surface properties of allophane such as adsorption and CEC. The purpose of the present study is to observe on change in surface properties of allophane after alkaline treatments.
