Abstract

Adsorption is one of the most effective methods used to remove reactive dyes from wastewater and, different adsorbents such as activated carbons, biosorbents and clay minerals can be used for the adsorption.In this study, the adsorption of Reactive Red 141 dye on montmorillonite based commercial organoclay compounds and the organoclay modified with hexadecyltrimethylammonium bromide was investigated and a high color removal was observed. The adsorption kinetics were modelled using pseudo first and second order kinetic models. The pseudo-second kinetic model was found the best fitted.
