Abstract

A rapid potentiometric method for determining fluoride in vegetation is described. Recovery of flouride by extraction with concentrated mineral acids compares favourably with standard methods of analysis in terms of accuracy and precision. The procedure affords the additional advantage that several citations are also quantitatively extracted and may be determined directly in the acid digest by atomic absorption spectrophotometry.

摘要

本文描述了一种测定植物中氟化物的快速电位分析法。用浓无机酸萃取氟化物的回收率在准确性和精密度方面与标准分析方法相比具有优势。该方法还有一个额外的优点，即几种微量元素也能被定量萃取，并且可以通过原子吸收分光光度法直接在酸消解液中进行测定。
