Since analysis of high purity Zn metal and ZnCl2 70% solution is in strong demand recently, spectrochemical analysis by solution DC-arc method was studied, as follows: (1) Zn concentration in the sample solution is heightened by HCl containing a small quantity of H3PO4 (H3PO4 prevents the evaporation of impurity Sn in the form of SnCl4). (2) The various factors and the condition levels which affect the sensitivity of this method are determined by (5×5) Graeco-Latin square experimental designation. (3) The sensitivity is expanded about to twice by duplicate exposure, and (4) the optimum analytical line pairs are selected by the variation coefficients calculated from 70 repeated analysis. This spectrochemical method can be applied to industrial routine analysis, in which the impurities Cd, Cu, Fe, Mn, Pb and Sn are present in the order of 10−4%, with the precesion of 7% in term of variation coefficient at above S (Opt.d.)=0.4 of impurity line.
