Kinetics of Methylene Blue Sorption on Polystyrene/Bentonite/Magnetite-Film Composites

Аннотация

Polystyrene/bentonite/magnetite-film composites were prepared by the method of mechanical dispersion of magnetized clay particles in a polystyrene matrix. The kinetics of Methylene blue sorption on polymer composites containing different filler amounts was studied. It was shown that with increasing bentonite/ magnetite concentration of composite to 5 wt %, the amount of sorbed dyestuff increases by seven times. It was found that Methylene blue sorption follows the equation of pseudo-first-order reaction kinetics.
