Pd is widely used in industries due to its unique property of catalyst and hydrogen storage.However,due to the low extraction efficiency of metal Pd,and a certain amount of metal Pd cannot be effectively recovered after usage,resulting in large amount of waste.2-methylimidazole zinc salt (ZIF-8)/polyvinylidene fluoride (PVDF) hybrid membrane was successfully synthesized by in situ method.Pretreatment of ZIF/PVDF hybrid membranes by adding different ratios of PEI and PAAS polyelectrolytes were performed.The effect of hybrid membranes on the retention of metal Pd were investigated and the extraction performance of palladium-containing solutions with different concentrations under different polyelectrolytes were examined.
