✦ Synopsis
An electrothermal atomization atomic absorption spectrometric method for the determination of traces of nickel atIer extraction of the metal into methyl isobutyl ketone containing 1,5-bis[phenyl(2-pyridylhnethylene
] thiocarbonhydrazide is suggested. The chief advantage of the method lies in its maximum allowable aqueous-to-organic phase volume ratio of 37. The method was applied to the determination of nickel in various biological tissues, serum and human urine.
