Polycyclic aromatic hydrocarbons(PAHs)are persistent and widespread in the aquatic environment,causing potential hazards for human health.In this study,a superwetting and robust PES-PAA-ZrO2 nanofiltration membrane was proposed through surface modification for PAH removal with high effi-ciency.A ZrO2 coating was formed on polyethersulfone(PES)membrane surface through chemical bonding,thus the PES-PAA-ZrO2 membrane exhibited super-hydrophilicity,under-water oleophobic-ity,and excellent stability.In comparison with the original PES membrane,the water contact angle of the modified membrane was significantly decreased from about 50° to less than 10°,and quickly dropped to 0° within 1 s.This provided a much lower energy barrier for water permeation due to its super-high water affinity.The wastewater treatment efficiency was increased by about 4 times after modification with more than 90％of PAH rejection rate.The excellent robustness of PES-PAA-ZrO2 membrane was verified under various conditions,which gave the membrane practical potential for long-term operation.
