Synthesis of a Gum rosin alcohol-poly(acrylamide) based adsorbent and its application in removal of malachite green dye from waste water

Abstract

The present paper is focused on the synthesis of a green GrA-cl-poly(AAm) adsorbent using N,N′-methylene-bis-acrylamide and potassium persulphate as a crosslinker–initiator system. The synthesized adsorbent was found to remove 83% of the toxic malachite green dye from aqueous waste water. Kinetic studies of the adsorption of the dye on the adsorbent showed pseudo second order kinetics and was found to fit well with the Langmuir isotherm model.
