Effect of Few Parameters on Removal of Atrazine from Waste Water

Abstract

The biosorbent IITB-LP emerged out to be the best absorbent on all counts and was selected for detailed biosorption study. Sorption equilibrium studies were conducted to establish the biosorption uptake capacity of the biosorbent. The biosorption kinetics was studied at different initial concentrationsThe removal rate was found to be increasing with anincrease in the initial atrazine concentration and with decreasing biosorbent size. The reaction followed Lagergren's pseudo 2nd order reaction kinetics. The biosorption of atrazine ontobiosorbent followed Langmuir isotherm model. It was found that the biosorption process of atrazine was controlled by intra-particle diffusion, which was confirmed by various kinetic studies and interruption test.
