摘要
建立了碱溶-离子色谱法测定次氧化锌中氯离子的分析方法。采用碳酸钠半熔-水浸出方法预处理样品,阳离子交换树脂去除重金属离子,以碳酸钠(2.5 mmol/L)和碳酸氢钠(3.5 mmol/L)混合溶液作为淋洗液,离子色谱法测定样品。方法的平均加标回收率为98.60%,检出限为0.015%。本方法灵敏度高,精密度好,预处理样品简单,易于操作,适合批量样品的测定。
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 for sample pretreatment, cation exchange resin for removal of heavy metals, and sodium carbonate （2.5 mmol/L） and sodium bicarbonate （3.5 mmol/L） mixture solution as eluent, the content of chloride ion in the sample was 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, simple in the pretreatment of sample, easy to operate, and suitable for determination of batch samples.
