| Abstract: | The low temperature plasma treatment with oxygen for PAN film ultrafiltration membranes are studied in this paper.The results showed that the water flux of the modified membranes decreased,but the rate of rejection increased.The influence oxygen low temperature plasma conditions (the input electricity power,the relative chamber pressure,the treating time) on the modification were studied.The results obtained indicated that the technique of surface modification by low temperature plasma treatment with oxygen is available in PAN ultrafiltration membranes modification. |
