摘　　要：实验采用丙三醇作为稳定剂,增强了氯化银比浊溶液的稳定性,讨论了氯化银比浊法测定湿法炼锌过程中氯离子的条件,该方法在测定过程中,其它共存离子的干扰较小,氯比浊线性范围0~350μg/25 m L,方法检出限为10μg/25 m L,加标回收率92.6%~104.3%,方法简便、快速,经实践用于测定湿法炼锌过程溶液中微量氯离子,效果良好。The stability of silver chloride turhidimetry mlution is increased by using glycerol as stabilizer in the test. the determi- nation on chloridion during zinc haydrometallurgy process by silver chloride turbidimetric method is discussed; in the determination process, this method has a little disturbance to the other co - existing ion, the linear range of chlorine turbidimetry is 0 - 350μg,/25mL, the detection limit of this method is 10μg/25mL, the adding standard recovery rate is 92. 6% - 104. 3% , the method is simple, rapid, which is used for practical that trace chlorine ion determination in zinc haydrometallurgy process liquor, the effect is good.
