关于氟化盐中氟含量测定的比较和探讨

Comparison and Discussion of Determination of Fluorine Content in Fluoride

氟化盐中氟含量用硝酸钍容量法和氟氯化铅-EDTA容量法测定的比较和探讨,主要是对氟化盐中氟化铝和冰晶石用两种分析方法测定之后分析数据与标准允差的比较,探讨两种方法中那一种更适合其中氟化铝和冰晶石中氟含量的测定。

Fluorine content in fluoridation salt was compared and explored by Nitric acid thorium and EDTA capacity measuring,mainly compared the afterward analysis data and standard difference of fluoridation aluminum and ice crystal stone in fluoridation salt by two types of analysis methods,to discuss which method was more suitable to measure the fluorine content in fluoridation aluminum and ice crystal stone.
