饲料级磷酸氢钙中氟的几种分析方法比较

The Conparison of Analysis Methcd of Fluorine in Feed Grade Dibadic Calcium Phosphate

本文采用茜素络合酮比色法和氟离子选择电极法对饲料磷酸氢钙进行氟的测定实验对比,得出常用的氟离子选择电极法完全可以代替经典的蒸馏比色法的结论。

In this paper, fluorine in feed grade dibasic calcium phosphate was determined by distillation colorimetric method and fluorine ion selective electrode method. In the result, general fluorine ion selective electrode method could be substituted for classical distillation colorimetric method.
