摘要
研究了叶蜡石中微量氟的分离测定方法。指出,用H3PO4—HClO4(2+1)蒸馏法分离微量氟,大量铝不干扰,故可将其用于各类高铝物料中微量氟的分离,继而用镧—茜素络合腙分光光度法测定其含量,获得了比较满意的结果。方法已应用于叶蜡石矿中微量氟的分离和测定。
A method for separation and determination of trace Fluorine has been studied It is shown that the interference of the Aluminum in large amounts can be eliminated when the Fluorine is separated by distillation method using H3PO4-HClO4(2+1)So it can be used to separate the trace Fluorine from the miscellanceous high-Aluminum materials and then it is determined by La-Alizarin complexone spectrophotometry The method is used to determine the trace Fluorine in Pyrophyllite with satisfactory results
