Resumo: A simple and selective method for separation and preconcentration of nickel has been developed. The method is based on the flotation of a complex of Ni and dimethylglyoxime (DMG) at the aqueous solution-n-hexane interface. The complex was separated and Ni determined spectrophotometrically by DMG after addition of oxidizing agent. The quantitative flotation of the complex was possible in the pH range of 9-12. The method is simple and free from the interference of all cations and anions and has a wide linear range. The procedure was successfully applied to the determination of trace amounts of nickel in well water and waste water in coating plant. The method's accuracy was investigated by using standard reference materials alloys (NIST 864) and by spiking the samples with different amounts of Ni2+.
