Abstract The present paper describes the determination of trace Ni, Fe, Mo , Mn and B in Ti/TiC composite material using carbon powder, calcium carbonate, cupric oxide and beryllium oxide as buffer by atomic emission spectrometry(ASE). Be 298.61 nm was selected as internal standard line. Sample separation and chemistry treatment were not requirel. The sample was directly loaded into ordinary electrode. The method is simple, rapid and accurate. The requirement of determination, and factors of influence were studied. A new method has developed for the determination of Ni, Fe, Mo, Mn and B. The analysis lines of Ni, Fe, Mo, Mn and B are 300.36, 248.33, 315.82, 260.57 and 249.68 nm respectively. The internal standard line of Be is 298.61 nm. The linear ranges of the determination of Ni, Fe, Mo, Mn and B are 0.003%-0.30%, 0.001%-0.20%, 0.003%-0.30%, 0.001%-0.20%, 0.001%-0.20% respectively. The detection limits of Ni, Fe, Mo, Mn and B are 0.003%;0.001%, 0.003%, 0.001% and 0.001% respectively. The ranges of the recovery of Ni, Fe, Mo, Mn and B are 95.80%-104.8%, and the standard relative deviations(RSD) are less than 5.0%(n=9). The method has been applied to the determination of Ni, Fe, Mo , Mn and B with satisfactory results.
