Abstract: Polyacrylamide-divinylbenzene functionalized Fe3O4/coconut shell adsorbent (MCSBR) was prepared by simple suspension polymerization method. The samples were characterized by FTIR, SEM and Zeta potentials. On this basis, the adsorption performance of MCSBR was studied by acridine orange(AO) as the model. Effect of experimental parameters including pH, shaking time, initial concentrations, temperature and ionic strength on adsorption capacity of MCSBR were studied. The adsorption kinetics was fitted with pseudo-second-order kinetics model better. Adsorption equilibrium of AO on MCSBR was evaluated using Langmuir and Freundlich models. Adsorption data of AO on MCSBR was fitted well with Freundlich model than Langmuir model. Moreover, MCSBR also showed excellent reusability by consecutive sixes cycles of adsorption-desorption. So it is environmentally friendly and low-cost adsorbent for removal of dyes in aqueous solution.
