液体氯化钡的几种分析方法的讨论

Discussion of Several Analytical Methods of Liquid Barium Chloride

对液体氯化钡的三种分析方法 -EDTA络合滴定、氧化还原滴定和重铬酸钾法(重量法)进行了对照实验,发现EDTA络合滴定法快速、准确、分析成本低等优点,满足中盐吉兰泰盐化集团有限公司现有的生产需求,建议采用EDTA络合滴定法分析20%液体氯化钡。

Three liquid barium- EDTA complexometric titration analysis,redox titration and potassium dichromate method（ gravimetric method） were conducted a controlled experiment,which found that EDTA complexometric titration was with fast,accurate,low cost analysis of 20% liquid barium chloride to meet the needs of our existing production. Then it was proposed the EDTA complexometric titration.
