Sustainable method towards magnetic ordered mesoporous polymers for efficient Methylene Blue removal

摘要

The difficulty in achieving high removal efficiency for contaminants in textile wastewater over a wide range of p H impedes the progress of its treatment technique greatly.Herein,a facile and sustainable strategy was adopted for constructing magnetic ordered mesoporous polymers(M-OMPs)without the assistance of organic solvent and catalyst.The prepared M-OMPs were endowed with high special surface area and good superparamagnetism simultaneously,and exhibited high removal efficiency(>99%)for Methylene Blue(MB)within a short time(10 min)at a concentration of 50 mg/L.What’s more,high removal efficiency was achieved over a wide range of p H 2-12 and the adsorption capacity for MB on M-OMPs was substantially retained even after 5 adsorption-desorption cycles,further demonstrating the application potential of M-OMPs in the decontamination of textile wastewater.
