Abstract
An electrothermal atomization atomic absorption spectrometric method f or the determination of traces of nickel after extraction of the metal into methyl isobutyl ketone containing 1,5-bis[phenyl(2-pyridyl)methy lene) thiocarbonhydrazide is suggested. The chief advantage of the met hod lies in its maximum allowable aqueous-to-organic phase volume rati o of 37. The method was applied to the determination of nickel in vari ous biological tissues, serum and human urine.
