电导率法测定甜菜碱灰分的研究

Conductometric method for determining the ash content of betaine

介绍了利用电导率测定甜菜碱硫酸灰分的方法。依据电导率与灰分含量呈线性关系,建立标准工作曲线进行定量分析。此法显著地降低了化验时间,可以满足实际测定的需要。

The conductometric method for determining the sulphated ash content of betaine is discussed in this paper. Based on the linear relationship between conductivity and ash content, standard working curve has carried on the quantitative analysis. This method reduces the test time obviously and can meets the needs of actual determination.
