| 摘 要： | 对盐垢中硫酸根的测定方法——铬酸钡光度法进行了改进,改进后的方法易操作,且非常稳定,相应工作曲线的相关系数达0.999以上,标准偏差低于0.005,回收率为99%～104%,具有较好的精密度和准确度。经用离子色谱法进行验证,测量结果的相对差值在0.001g/L以下。同时,改进后的方法也适用于测定水垢中硫酸盐的含量。

| Abstract: | The method for determining sulphate content in salt deposit has been improved by using barium photometry after improvement,the method is easy in operation,and being very stable.The related coefficient of corresponding working curves reaches above 0.99,the standard deviation being less than 0.005,the recovered rate being 99%~104%,boasting better precision and accuracy.Through verification by using ion chromatography,it shows that the relative difference value is below 0.001,boasting higher accuracy. |
