Use of masking agents in the determination of lead in tap water by flame atomic absorption spectrometry with flow injection pre-concentration.

Abstract

The selectivity of immobilised 8-hydroxyquinoline for lead is shown to be improved by the use of masking agents during pre-concentration, prior to determination by flame atomic absorption spectrometry. Interference by iron, copper, aluminium and zinc is suppressed by including triethanolamine, thiourea, fluoride, acetylacetone or cyanide in the buffer as… (More)
