Abstract

Adsorption methods are among the most promising water treatment approaches of today. Application of clay materials as sorption agents for surface and waste water treatment are of particular interest. The object of current study is bentonite mainly containing montmorillonite. The micro- and meso-porosity of bentonite can be increased by introduction of pillars into the interlayer structure of aluminosilicates. The work describes a technology for bentonite gel production by modification of bentonite by glycerol. The elemental composition of bentonite was investigated by electronic microscopy of the specimen surface. The analysis of electronic microphotograps of the side face and side surface of the granules of annealed modified bentonite specimen and results of electronic microscopy have shown that bentonite granules during annealing are modified by pyrolysis carbon produced after decomposition of glycerol in oxygen-free atmosphere. It was established that bentonite modified by glycerol has four times larger specific surface area as compared with non-modified bentonite.
