| Abstract: | In the industrial production of sodium carbonate using ammonium bicarbonate and sodium chloride as raw materials, co-existing ions Na +? HCO - 3? CO 2- 3? NH + 4 and Cl - were found in the mother liquor of the intermediate product. Titrimetric method for the determination of HCO - 3? CO 2- 3? NH + 4 and Cl - ion was described as intermediate control test. Sodium ion was determined by the conventional ISE method. |
