萤石中氟化钙的测定,多是通过测定钙换算成样品中氟化钙含量。这些测定方法操作繁琐,准确度低。近年来有人试图用氟离子选择性电极测定氟矿中的氟含量,只是应用上的报导还不多。本文研究了热解-电位滴定及酸碱滴定测定萤石中氟化钙的适宜条件,并提出了简单快速、切实可行的分析方法。
Calcium fluorite fluorite determination, mostly by measuring the conversion of calcium into a sample of calcium fluoride content. These assays are cumbersome to operate and less accurate. In recent years, some people tried to use fluoride ion selective electrode fluorine content in fluorine ore, only the application of the report is not much. In this paper, pyrolytic - potentiometric titration and acid-base titration of fluorite fluorite in the determination of the appropriate conditions, and put forward a simple, rapid and practical analytical methods.
