Simultaneous Determination of Cadmium, Chromium, Lead, and Manganese in Smoke from Burning Oil by Impaction Graphite Furnace Atomic Absorption Spectrometry

Abstract Impaction‐graphite furnace atomic absorption spectrometry (I‐GFAAS) has been used to directly and simultaneously determine cadmium, chromium, lead, and manganese in the smoke or plume from burning crude oil in laboratory‐controlled conditions. Concentrations in the low ng/m3 can be determined for all four metals. Cadmium and lead appear in the smoke in the first 30 sec of the burn whereas up to 120 sec is required for all the chromium and manganese to be found in the smoke.
