Trace enrichment and determination of gold by flow injection inductively coupled plasma spectrometry. Part 1. Inductively coupled plasma atomic emission spectrometry

Abstract

Flow injection systems incorporating microcolumns of Amberlyst A-26 and sulfhydryl cotton were combined with inductively coupled plasma atomic emission spectrometry for on-line preconcentration and determination of gold in waters. Use of a sampling volume of 10 ml and an eluent volume of 250 µl resulted in preconcentration factors of 40 and 50 with Amberlyst A-26 (eluent, ammonia solution) and sulfhyrdyl cotton (eluent, potassium cyanide solution), respectively. The limit of detection was about 1 µg l–1(for both microcolumns) and the precision was 1.2–3.5% at the 50 µg l–1 level. Application to the determination of gold in refinery effluent was demonstrated.
