摘要
Abstract
This paper modified graphene oxide(GO)with ethylenediamine and gallic acid to fabricate a membrane.It characterized the membrane structure using FTIR and XRD.Meanwhile,the wettability,pure water flux,separation performance(for kerosene-in-water and crude oil-in-water emulsions),recyclability,and acid-base resistance of the membrane were evaluated.The results show that the modified GO with ethylenediamine and gallic acid(GA-EGO)membrane has a pure water flux of 1 033.2 L/(m2·h).This value is 1.8 times higher than that of the pristine GO membrane(581.4 L/(m2·h)).The GA-EGO membrane shows superhydrophilicity in air(water contact angle of 0°)and superoleophobicity underwater(oil contact angle of 150.1°).It effectively separates various oil-in-water emulsions.The kerosene emulsified oil removal rate of GA-EGO membrane reaches 97.2%,which is 19.8 percentage points higher than that of the GO membrane.Furthermore,the GA-EGO membrane demonstrates excellent recyclability and acid-base resistance.关键词
