摘要：

A method is described for the determination of trace amounts of phosphorus, arsenic or silicon by atomic absorption spectrometry. The heteropoly-molybdo acids of phosphorus, arsenic and silicon were formed and selectively separated by means of solvent extraction, and the molybdenum present in the organic phase was determined by atomic absorption spectroscopy with a nitrous oxide-acetylene flame. The method is rapid, simple and accurate and is essentially free from interferences. © 1969.
