Specific gravity and sorption characteristics of water purifying composites

Abstract

The specific surface area obtained from activated carbon, silica, kaolin and synthetic silver (BAKS-001, BAKS-002, BAKS-003) has been determined. Their specific surface area was determined by the method of adsorption of butanol in the composites, r 938, 954, 1008 m 2/g. respectively. The mechanism of butanol sorption was considered The specific surface area of a number of composites obtained from activated carbon, silica, and the increase in the contribution of the dipole-dipole interactions sorbent-sorbate in a series of BAKS-001 <BAKS-002 <BAKS-003 was shown .An increase of the cation exchange properties of a number of adsorbents has been determined. The maximum capacity of the ions exchange of Fe3+ (2.14 mmol/g) in the case of composite-BAKS 003 was obtained by pretreatment of the activated carbon by concentrated sulfuric acid.
