Study on the Determination of Content of Fluorine in Rare Earth Fluoride
The Fluorine is combined with rare earth element quantitatively, the content of rare earth element is determinated by EDTA method, which could determinate the content of Fluorine.The effects of acidity and buffer solution on the result is studied, as well as the elimination condition for impurity interference.The rate of recovery is between 98.67% and 100.45%, the standard deviation is less than 0.21%.
