Differential spectrophotometry of nickel as its pyridine-2,6-dicarboxylic acid complex.
The determination of nickel with pyridine-2,6-dicarboxylic acid by means of differential spectrophotometry at 1,025 mmicro is described. At the Ni concentration level of 2 mg/ml the relative standard deviation is 0.1 %. Only a few elements interfere.
