The mutal influence of Fe, Si, Mo, Nb, Cr, Al, Ti, Ni on the spectrographic determination of these elements as trace impurities in tantalum pentoxide matrix has been investigated. In a preliminary experiment designed according to Plackett and Burman the influence of Fe and Al proved to be insignificant. Consequently both elements were excluded from further investigations. Based on experiments carried out on standard samples whose compositions resulted from factorial plans 2n, 3n, rotatable composite design and conventional calibration methods, the mathematical models of interference effects were fitted. In all the cases studied it was found that the correction of analytical results for the interference effects by means of polynomial models containing concentrations of interferents, was more effective than by means of conventional calibration methods. Those models in which a logarithmic analytical function was applied, proved to be most effective.
