| Abstract: |
| An analytical method for the determination of chloride in Zinc hypoxide by using alkali fusion for sample preparation and ion chromatography was established. Using sodium carbonate semi molten-water leaching method of sample pretreatment, removal of heavy metals by cation exchange resin, sodium carbonate (2.5 mmol/L) and sodium bicarbonate (3.5 mmol/L) mixture solution as eluent, samples were determined by ion chromatography. The average recovery rate of the method is 98.60%, the detection limit is 0.015%. This method is of high sensitivity, good precision, the pretreatment of the sample is simple, easy to operate, and suitable for the determination of batch samples. |
