Quantitative analytical condition for nickel in ceramic, metal and plastic materials using complexation and solvent extraction followed by inductively coupled plasma-atomic emission spectrometry (ICP-AES) and atomic absorption spectrophotometry (AAS) was studied. Ceramic, metal and plastic samples were dissolved by acid digestion. Nickel was determined by ICP-AES and AAS after extraction of Ni (DMG)_2 in CHCl_3. Recovery efficiency of nickel was satisfactory, and most of matrix elements causing interference could be effectively eliminated by the separation. Nickel in the certified reference materials (BAM-376 and PACS-2)were quantitatively determined without influence of sample matrix.
