The extraction of molybdoarsenic acid with trioctylamine into molten stearic acid and extraction X-ray fluorescence determination of arsenic

Creators

Description

An X-ray fluorescence method of trace arsenic determination has been developed. The method is based on extraction of molybdoarsenic acid with trioctylamine into molten stearic acid. The influence of various factors on the extraction has been studied. The optimal extraction conditions have been studied. The method was used for the analysis of food stuffs. 10 refs., 5 figs., 2 tabs
