Loess Composited PMAA-CS for Removing Methylene Blue

Article Preview

Abstract:

Dyes have made a great contribution to the progress of this beautiful and bright world,but a large amount of wastes containing dyes have been discharged into the receiving aquatic environment. In this paper, a loess composited polymer adsorbent, poly (methacrylic acid)-grafted chitosan/Loess composite (PMAA-CS/ LC), was applied to remove methylene blue (MB). It was found that the removal rate of MB reached to 98.6% under the optimal condition of adsorption. Adsorption dynamics were consistent with pseudo-second-order kinetic model and isotherm model can meet the Langmuir isotherm model.
