The Determination of Metals in Sediment Pore Waters and in IN HCl-Extracted Sediments by ICP-MS

摘要

Concentrations of metals In sediment Interstitial water (pore water) and those exiractable -from sediment with weak adds can provide Important information about the bioavailabllity and lexicological effects of such contaminants. The highly variablenature of metal concentrations in these matrices requires Instrumentation with the detection, limit capability of graphite furnace atomic absorption and the wide dynamic linear range capability of ICP-OES. These criteria are satisfied with ICP-MS Instrumentation. We Investigated the performance of ICP-MS in the determlnation of certain metals from these matrices. The results for three metals were compared, to those determined by graphite furnace atomic absorption spec-troscopy. It was concluded that ICP-MS was an excellent instrumental approach for the determination of metals in these matrices.
