Abstract
Abstract An ICP-AES/GFAAS method is described for the determination of metals in sewage sludges following acid digestion in a microwave oven. Application of the method to BCR 144, 145 and 146 sewage sludge standards, gave results in agreement with BCR values. Recoveries were in the range 90-109% for HF/aqua regia digestion. Analysis of aqua regia extracts by ICP-AES was shown to produce data comparable to those reported by BCR.
