Treatment of methylene blue containing wastewater by a cost-effective micro-scale biochar/polysulfone mixed matrix hollow fiber membrane: Performance and mechanism studies

摘要

Graphical abstractDisplay OmittedHighlights?A cost-effective biochar/PSF mixed matrix membrane was developed.?The removal of methylene blue was not very sensitive to pH and salt concentration.?The adsorption process was well controlled by intraparticle surface diffusion.?The MMM showed an excellent reusability for methylene blue removal by filtration.?The adsorption is related to electrostatic, hydrophobic and H-bonding interactions.AbstractDye containing wastewater has increasingly become an important conta
