| Abstract: | The feasibility of dealkaline of raw sodium tungstate solution by diffusion dialysis has been studied. The effects of feed and dialysate flow rate, the concentration of free alkaline in the feed and initial alkaline concentration in the dialysate solution on the dialysis flux of alkaline, flux of H2O and the mass transfer dialysis of tungsten are investigated. The experimental results show that the alkaline can be separated and recovered from raw sodium tungstate solution by diffusion dialysis effectively. |
