Analysis of heavy metals and fluoride in vegetation by extraction with concentrated mineral acids.
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.
