Abstract: A polyvinylidene fluoride hollow fiber membrane impregnating a palladium nano cluster is provided to improve efficiency of removing an underwater dissolved oxygen and profitability and to use separate chemical substances. A polyvinylidene fluoride hollow fiber membrane impregnating a palladium nano cluster of which a size of particles is 20 ~ 50 nm inside pores has whole porosity of 65 ~ 70 %. A specific surface area of a surface of the polyvinylidene fluoride ultrafiltration membrane is 150 ~ 200 m^2/g. The 0.07 ~ 0.21 weight% of palladium nano cluster is impregnated to the polyvinylidene fluoride hollow fiber membrane.
Abstract translation: 提供浸渍钯纳米簇的聚偏氟乙烯中空纤维膜，以提高去除水中溶解氧的效率和利润，并使用单独的化学物质。 在孔内浸渍粒径为20〜50nm的钯纳米簇的聚偏二氟乙烯中空纤维膜全孔隙率为65〜70％。 聚偏二氟乙烯超滤膜表面的比表面积为150〜200m 2 / g。 将0.07〜0.21重量％的钯纳米簇浸渍到聚偏二氟乙烯中空纤维膜上。
