Study on Synergistic Removal of Methylene Mlue and Hexavalent Chromium from Water by Activated Carbon
By adjusting the dosage of activated carbon and the adsorption reaction time,the optimal reaction conditions for the adsorption of methylene blue and hexavalent chromium on activated carbon at room temperature were obtained,and the adsorption kinetics model for the adsorption of methylene blue and hexavalent chromium on activated carbon was simulated.Further exploration was conducted on the synergistic removal effect of activated carbon on methylene blue and hexavalent chromium.The results indicate that activated carbon has a synergistic effect on the removal of methylene blue and hexavalent chromium in aqueous solution.Under the presence of methylene blue,activated carbon has a certain promoting effect on the removal of hexavalent chromium,while the presence of hexavalent chromium has little effect on the removal of methylene blue by activated carbon.
