摘　　要：采用共沉淀法制备了CuO纳米片,将CuO纳米片通过加压和抽滤固定方式负载到纤维膜表面,制成催化分离膜。在温度25℃、pH 7、过一硫酸盐浓度为0.5 mmol/L、CuO纳米片负载量为79.58 g/m 2、驱动压力为5×10-3 MPa的条件下,催化分离膜在10 min内对20 mg/L亚甲基蓝(MB)溶液的去除率达到98%以上,纯水通量为457 L/(m 2·h)。通过自由基捕获实验确定1O_(2)是催化分离膜降解MB的主要活性氧物种。CuO nanosheets were successfully prepared by the co-precipitation method.CuO nanosheets were loaded on the fiber membrane by pressure and filtration to prepare the catalytic separation membrane.The removal rate of 20 mg/L methylene blue(MB)can reach 98%win 10 minutes with the pure water flux of 457 L/(m 2 h),under the conditions of temperature 25℃,pH 7,peroxymonosulfate concentration of 0.5 mmol/L,CuO nanosheet loading of 79.58 g/m 2 and driving pressure of 5×10-3 MPa.The radical quenching experiments confirmed that 1O_(2)was the main reactive oxygen species for the degradation of MB by the catalytic separation membrane.
