- Abstract
- Acrylamide/itaconic acid (AAm/IA) hydrogels containing different
quantifies of itaconic acid have been irradiated with gamma radiation. The
hydrogels were used in an experiment concerning the adsorption of cationic
dyes such as Basic Blue 9, Basic Violet 1 and Basic Blue 12. In the
experiments of the adsorption of dyes from their synthetic aqueous solutions,
type S adsorption isotherms were found. One mole of monomeric unit of AAm/IA
hydrogels adsorbed 78.5-513.1 mu mole of Basic Blue 9, 60.2-641.1 mu mole of
Basic Violet 1 and, 28.8-593.3 mu mole of Basic Blue 12, while acrylamide
hydrogel did not adsorb any cationic dye. As a result, if was shown that the
AAm/IA hydrogels could be used as an adsorbent for water pollutants such as
dyes, and immobilization of these organic contaminants in the hydrogels from
waste wafer can solve one of the most important environmental problems of
the textile industry. (C) 1997 by John Wiley & Sons, Ltd. [References:
