Open publisher page 0 citations

Abstract

In this paper,the trace Pb 2+?Cd 2+ and Cu 2+ were determined by Flame Atomic Absorption Spectrometry after being enriched with vulcanized-cotton. The optimum conditions of separation?enrichment were studied. The recovery is 99%～102%. RSD is 2.8%～6.8%. It was used to determine trace Pb 2+?Cd 2+?Cu 2+ in tap water and other water samples with satisfactory results.
