Abstract
The amount of hydroxyl and alkyl groups on the surface of sorbents synthesized by chemical modification is determined. The interaction of chlorosilanes and organosilanes with the kaolinite surface is investigated. A correlation between the pH value of a suspension of the obtained sorbent and the amount of active sites on its surface is established.
