Preparation of Nanoporous Polymer Separation Membranes and Their Oil-water Separation Properties
Objective:To prepare nanoporous polymer separation membranes and investigate the oil-water separation performance of the membranes.Methods:Zinc nitrate hexahydrate,aluminum nitrate ninahydrate,chromium nitrate ninahydrate and other raw materials were used to prepare the separation membrane,simulate the complex industrial environment,and test the separation of oil and water.Results:The maximum oil-water separation cycle of the nanoporous polymer separation membrane was 11 times,and the particle size of oil droplets on the separation membrane was distributed in the range of 1 500~2 000 nm.Conclusion:The nanoporous polymer separation membrane has a good separation effect on oil droplets in a specific particle size range when treating oil-water mixtures or similar systems.
