Description

To determine optimum working conditions for spectrochemical analysis of the impurities in ammonium pa atungstate by the Carrier-Distillation Method, <BR>(i) the author determined the degree of suppression of tungsten spectrum numerically by the equation, <BR>E=S3/S1+S2<BR>where, S1+S2= intensity of tungsten spectrum lines.<BR>S3=intensity of impurity spectrum lines.<BR>(ii) he then applied the statistical techniques in experiments, i. e., the orthogonal array method in the first experiment, and, randomized block method in the second experiment, taking E as the characteristics.<BR>In spite of the existence of many unknown factors which might affect the results of analysis, the optimum conditions are thus obtained very efficiently.
