摘　　要：建立了氯化银比浊法测定镍钴锰三元素氢氧化物中氯离子含量的测定方法。选择了合适的测定波长,并对硝酸用量、沉淀剂用量、稳定时间对测定结果的影响进行了试验,确定了较优的分析条件。样品加标回收率在95%-103.3%,氯离子浓度在0-4μg/mL与浊度值有良好线性关系。方法为控制镍钴锰三元素氢氧化物中氯离子提供了检测依据。A novel method for the determination of chloride ion content in nickel cobalt manganese composite hydroxide by silver chloride turbidimetry was studied.The influence of wavelength,nitric acid volume,precipitant volume and stabilization time were investigated to obtain the optimized test conditions,respectively.The recovery was 95%-103.3%.The analytical results showed that there is a good linear relationship between chloride ion concentration and turbidity value when the chloride ion concentration is in the range of 0-4μg/mL.The proposed method has been applied to the determination of chloride ion in nickel cobalt manganese composite hydroxide samples with satisfactory results.
