Following after the previous report1), we investigated the hindrance expected to occur in the process of the paperchromatographic total analysis of metalic ions by using the three developers (as indicated in Table 1). At first, we investigated wether 100γ of the ions hindered or not the detection of 2γ of the other ones which had near Rf values to those of the formers, and found that by using selected color reactions (as showed in Table 1 and 2) such hindrance could scarcely occur. Secondary we investigated hindrance caused by 100γ of the anions which disturbed the ordinary systematic analysis, and found that those anions moved with their own Rf values apart from the metalic ions, and hardly affected the Rf values and detective reactions of the cations (as showedl in Table 3). Further more we found that Hg+2, Sn+2 and Fe+2 were oxidized by air, MnO4 was reduced by filter paper and Fe+3 partialy turned into Fe+2 by light in the paperchromatographic processes.
