In electrochromatography, five kinds of different filter paper holders were used and the velocity of migration, area of colored band, and migration distance of each position on the filter paper were measured under identical conditions so as to examine the separatory ability and equality of rate of each apparatus. It was thereby found that the best separation is effected by placing the paper in a convex form, with the middle higher, while for uniform mobility, the filter paper should be cooled directly by closely adhering the lower surface on a cooling vat.

A filter paper wetted with an electrolyte was placed between two glass plates coated with a silicone resin. Electric current was passed through this paper in order to find the relationship between the time, voltage, electric current, and temperature with degree of mobility of numerous inorganic ions. It was found that a linear relation always existed, in any of the electrolyte used, between the distance of mobility and time and voltage. The effect of electric current was examined with sodium nitrate as an electrolyte and it was found that electric current did not influence the mobility of the ions as much as voltage. A metallic thermostatic vat, coated with insulating paint, was devised and the mobility of ions at various temperatures was examined and it was found that the mobility generally increased with the increase of temperature and this influence was found to be greater the larger the mobility of the ion. Influence of evaporation by the warming of the filter paper was quantitatively examined, using the Durrum apparatus, with either direct or alternative current as the electric source, from the relationship between the position of the sample placed and the distance of ionic mobility. It was thereby unexpectedly found that a great deal of effect was caused by evaporation.

By the use of the same method of capillary filled with alumina as given in the previous paper, order of adsorption, limit of detection, separation of several kinds of anions, and the method of microdetection of I^-, NO₂^-, and CN^- ions were examined. It was found that the separations of Cl^- and PO₄^---, Cl^- and AsO₄^---, PO₄^--- and AsO₄^----, AsO₃^--- and AsO₄^---, I^-, CrO₄^--, and PO₄^---, NO₂^- and CrO₄^--, were possible. The coloration reagents used were, besides the known AgNO₃ method, CuCl₂, Hg(NO₃)₂, FeCl₃, and benzidine. Chromatographic separation of metal complexes were also carried out by the same method and the separation of Cr and Pb, which was previously reported as being comparatively difficult was found to be possible by preparing a tartaric acid complex, while that of cobalt, nickel, and cadmium waa found to be possible by the ammonium complex method.

Relationship between the pH of the electrolyte solution and the degree of mobility was examined with inorganic ions. Electrolyte used were sodium nitrate, potassium thiocyanate, and tartaric acid series, and the ions detected were Ba⁺⁺, Pb⁺⁺, Cu⁺⁺, Zn⁺⁺, Ni⁺⁺, Fe⁺⁺⁺, Br^-, CNS^-, AsO₄^---, CrO₄^--, Fe(CN)₆^---, NO₂^-, and BO₃^---. Except in the case of extremely acid or alkaline range, the effect of pH was found to be rather small in inorganic ions in general, both in cations and anions. However, in the case of amphoteric metals, such as zinc, they behave similar to amino acids. Use of complex salt-forming electrolyte in the case of metallic ions, the effect of pH was found to be extremely great. In the case of tartaric acid electrolyte, metals were found to move as a cation in the acid range of lower pH while they behaved as anions in a higher pH range, and there is a certain pH (isoelectric point) at which each metal does not move at all. From these facts, it was found that the complex salt-forming electrolyte was suitable for the separation of metals.

A glass capillary of approximately 0.8mm. inside diameter and approximately 10cm. long, filled with alumina and having a pinhole at one end was used as a means of detecting several kinds of mixed ions by suction of sample solution and coloration reagents into the capillary through the pinhole. Limit of detection of metallic ions by various coloration reagents was examined and the present method was found to be far sharper than the paper spot test and the best suited for the detection of a minute amout of ions. The feature of this method may be said to lie in the fact that only a minute amount of sample and alumina are needed and that the procedure is simple and time short.

By the determination of the stepwise change of pH in the absorption tube during cation adsorption and the amount of cerresponding anion adsorbed, precipitation of basic salt of metals was assumed, and following tests were carried out. Hydrogen ion concentration at the time of precipitation was determined with glass electrode pH meter and the relationship between pH at the time of absorption and the amount absorbed were examined by static adsorption, and it was found that the precipitation pH range and the order of adsorption were in good agreement and that the adsorption of cation became maximum in the precipitation pH range. From these facts, it was assumed that the adsorption of metallic ions by alumina was chiefly due to the precipitation of their basic salts. It was also found that the influence of anions was rather great in the adsorption of mercury salt, as the adsorption of mercury became extremely small in the presence of a chloride and this was assumed to be due to the formation of mercuric chloride of small degree of dissociation.
