| Abstract: | The disposal of pregnant antimony solution in production of sodium bicarbonate was studied.On the basis of the theoretical analysis and experiment,a process flow with three-effect-evaporation to recover ammonium chloride and sodium was designed.In this process the mother liquor was evaporated cyclically,no waste fluid was discharged.The result shows that recovery ratios of ammonium chloride and sodium chloride are 46.24% and 72.27% respectively.Ammonium chloride product is up to standard. |
