摘要
建立了离子色谱法测定溴素中的游离氯的分析方法,确定了以亚硫酸钠为还原剂还原溴中的游离氯、水浴蒸发除溴的样品预处理方法及操作条件。方法相对标准偏差为0.68%~1.46%,平均加标回收率在97.4%。
The method for the determination of chlorine in bromine by ion chromatography is established . The method for pretreatment of sample is determined and the operating condition is discussed, The method for pretreatment is to remove bromine with water - bath evaporation and reduce free chlorine in bromine with sodium sulfite. The relative standard deviation is between 0.68% and 1.46%, the average recovery is 97.4%.
