【Abstract】 Membrane extraction model of Toluene TNT Water system was investigated , and mass transfer equation was obtained in this paper. The experimental result shows that the obtained mass transfer equation is acceptable and effective, with relative error under 10%. After comparing every mass transfer resistance during membrane extraction process, it is obtained that using hydrophobic membrane module in this system can effectively decrease the membrane resistance and enforce mass transfer.更多还原
