Özet

Acrylamide/itaconic acid (AAm/IA) hydrogels prepared by irradiating with gamma radiating were used in experiments on the uptake of some cationic dyes such as basic red 5 (BR-5), basic violet 3 (BV-3) and brilliant cresyl blue (BCB). The removal of the cationic dyes to AAm/IA hyrogels is studied by batch adsorption technique. In the experiments of the adsorption, L3 type (Langmiur) adsorption in Giles classification system was found. Adsorption studies indicated that monolayer coverages of AAm/IA hydrogel by these dyes were increased with following order; BCB > BR-5 > BV-3.
