摘要

以铬黑T(T)为主要原料

通过正交试验

筛选出微量硬度指示剂的新配方。试验结果表明

新配方可提高硬度检测的灵敏度

误差小

最低检测下限可达到0.15μmol/L(以Ca2+计)

适用于各种低硬度水的硬度检测。

Abstract

Taking chrome black T（T） as main material

a new prescription of trace hardness indicating agent has been screened out through orthogonal test. The test result shows that the adoption of said new prescription can enhance the sensitivity of hardness detection

having little error

and the lower limit of detection can reach 0.15μmol/L （estimated by Ca

2+ ）

being suitable for detecting hardness of various water with low hardness.
