Nano Chitosan Adsorption Of Yellow (W6GS) Dye

Abstract

The removal of yellow(W6GS) dye has been studied, by using Nano chitosan . Adsorption isotherms were studied under different Temperatures , the effect of salt ions and Equilibrium time were investigated  . Adsorption isotherms were found to be comparable to the Langmuir equation .the adsorption results were evidently increased with the high temperature (Endothermic process ).  The functions were calculated (∆H, ∆G, ∆S) were calculated. The Kinetics of the adsorption was studied. The results were treated according to (Lagergren equation). The Kinetic experimental data properly correlated with the pseudo First order kinetic model.
