Synthesis of zeolite-like crystals by means of sorption of bases on polysilicic acids

Journal Article:

Abstract

Investigation into the sorption of bases on crystalline polysilicic acids is of particular interest from the viewpoint of synthesis of new types of porous zeolite-like materials. A synthesis of polysilicate acids was carried out by treating respective sodium polysilicates with mineral acid solutions. The sorption of alkali metal hydroxides in the neutral and alkaline pH region was studied by the method of potentiometric titration of individual weighed quantities. A marked sorption of alkali metal hydroxides on polysilicic acids starts in the weakly acid and neutral regions and reaches saturation at pH=10.5. The process of ion exchange is accompanied by a change in the crystal structure of polysilicic acids. The sorption of bases on polysilicic acids may be used as a method of synthesis of zeolite-like porous crystals in different cationic forms.
