Determination of Trace Elements in Biological Tissues by Aluminum Block Digestion and Spike-Height Flame Atomic

School of Applied Science. Canberra College of Advanced Education P.O. Box I,Belconnen Act 2616, AustraliaReceived May 8,1985; accepted January 27,1986A method for the determination of cadmium, copper. lead, and zinc in biological tissuesusing small volumes of digest is described. An aluminium heating block is used to digestsamples and elements are determined by spike-height flame atomic absorption spectrom-etry. Interferences have been assessed and the sample decomposition procedure evalu-ated. 0 1W6 Academic ~SS. Inc.
