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