| Abstract: | In order to make an ideal microporous membrane ,the preparation conditions of PAN/PSF membranes were optimized by Random-Design method and SAS regression analysis software. Meanwhile, linear regression models of PAN/PSF membrane preparation conditions and membrane performance were set up to predict the performance of PAN/PSF membranes quantitatively. From the results of the experiment, it can be found that the pure water flux optimized is 3122 L/(m 2·h) and the average pore size optimized is 0.95 μm, about 1.7 and 1.8 times respectively of those unoptimized. |
