[Determination of lead, cadmium, mercury, chromium and arsenic in acrylonitrile-butadiene-styrene copolymer using microwave digestion-ICP-MS].

A method was studied for the analysis of Cr, As, Cd, Hg and Pb in acrylonitrile-butadiene-styrene copolymer by using ICP-MS. The instrument parameters were optimized and the introduction system was developed systematically. The sample is decomposed by microwave digestion.
