Abstract
Abstract Dichloromethane is newly investigated as a solvent for the differential pulse polarographic determination of nickel after solvent extraction with dimethylglyoxime. As little as 20 ng of nickel in sample solution can be selectively determined by the present polarographic method. This method is successfully applied to the determination of nickel in such samples as steel, aluminum and zinc alloy, river sediment with good accuracy and reproducibility.
