Abstract
The determination of nickel by ETA-AAS and ICP-AES in biological samples with prior extraction into methyl isobutyl ketone with 1,5-bis(di-2-pyridylmethylene) thiocarbonohydrazide as extracting reagent is described. Microwave dissolution in closed teflon vessels has been used for the dissolution of biological materials. At least three samples can be decomposed simultaneously with a preset heating programme. Results of analyses of some certified biological reference materials are given.
