Study on Adsorption of Methylene Blue by Sarch-g-Polyacrylamide

Abstract:

By means of grafting polymerization, cross-linked starch-g-polyacrylamide (starch-g-PAM) was prepared and used to adsorb methylene blue (MB). Adsorption isotherm and kinetic of the sorption process were studied. The experimental results demonstrated that the prepared starch-g-PAM was an effective adsorbent for removal of MB from aqueous solution. The adsorption of MB by starch-g-PAM was Freundlich type, and the adsorption equation was caculated to be . Furthermore, the adsorption kinetics analysis demonstrated that the adsorption process followed the pseudo-second-order model.
