抄録 1. Layers containing thermal water in this district are thin, and lie at different depths (about 35, 55, and 60 meters) from the ground surface. There are evidences to show that these layers are intimately connected with one another. 2. The authors may suppose the existence of a structurally weak zone, along the line from Matsuzaki to Asozu, within which the issuing spots of thermal springs are located. 3. The head water levels of the thermal springs in this district are closely related with that of Lake Togo. Keeping pace with the variations of the water levels of Lake Togo and of artesian wells in its vicinity, the rate of flow of thermal springs vary; and the correlation between these variations is apparent. 4. The pumping suction of thermal water at one spring affects the flow of water at other springs within distances of 150 to 200 meters therefrom, though the direct sources of thermal water supply for the latter springs may be different from that of the former. 5. The spring water in this district is considered to be a mixture of hot water, containing sodium, calcium, chloride, and sulfate ions, and cold water, containing bicarbonate ion. The diversity of chemical constitutions of different spring waters is explained as due to the difference in proportion in which the hot and cold waters are mixed.

抄録 The thermal and ground waters were sampled in the hot springs district of Hamamura-Katsumi and Shikano and in their neighborhoods. The water temperatures were measured when they were sampled. Among the major chemical constituents, the chloride, sulfate, bicarbonate (methyl-orange alkalinity), calcium and magnesium content was determined. Furthermore, as the minor constituents, the arsenic and phosphorus content was also determined. The uranium, radium and radon content was determined in some samples of hot springs. Based on the results of chemical analysis, the relations between the chloride content and the content of other chemical constituents were cheked respectively. Positive correlations were found in the relations between water temperature-Cl(-), SO(4)(2-)-Cl(-), Ca(2+)-Cl(-) and As-Cl(-), although the ratios of each content showed the different characteristic in Hamamura-Katsumi compared with that in Shikano. In the samples of Hamamura-Katsumi where the thermal waters were pumped out from the sedimentary beds of volcanic rocks, the sulfate and calcium content was relatively richer compared with the content of these ions in the samples of Shikano where granitic rocks underlay as the basement in the fairly shallow depth from the cground surface. These characteristics were also noticed when the chemical compositions of other hot springs in the central part of Tottori prefecture were examined. In the neighborhood of the hot springs district mentioned-above, distinctive indications of hot spring were found at Kinashi which was placed between Hamamura and Shikano, comprehensively examining the content of chemical constituents in the ground water samples in this region.

抄録 The chemical and physical characteristics of the thermal and ground waters in Sekigane Hot Springs were determined. The content of the following chemical constituents was determined: Cl(-), S0(4)(2-), HCO(3)(-), Ca(2+), As, F, U and Ra. The relationship between water temperature and depth of spring wens was found to be indicative of the presence of a fissure, in agreement with the conclusion reached geologically by Sugiyama. The water temperature, the e1ectricconductivity and the content of chemical constituents of the ground water were as expected markedly lower than those of the thermal water. As a whole, however, the water temperature, the electricconductivity and the content of SO(4)(2-), HCO(3)(-), Ca(2+), As and F are in positive and linear correlation with the Cl- content. In other words, these characteristics of the waters, excluding the U and Ra content, correlate positively and linearly with each other. This was interpreted to mean that a thermal water of high salinity is simply diluted by a cold ground water of very low salinity, and that a ground water of relatively high salinity is contaminated by thermal water. The content of U and Ra of these spring waters is lower than that of the spring waters in Ikeda, Shimane-ken, and Misasa, Tottori-ken, where radioactive springs also issue. Finally, it is concluded that As and F will be as useful as Cl- in chemically locating a new site for a spring well in Sekigane because of the low contamination due to human life of ground water by these elements.

タイトル(別表記) SPECTROPHOTOMETRIC DETERMINATION OF ZIRCONIUM

抄録 Neo-Thorin was previously presented by the other authers as a color-developing reagent for the spectrophotometric determination of zirconium. 1) To determine the optimum condition for the use of this method, the effects of pH, time and temperature, and the interference of several ions were checked. The following conclusions were derived from the experimental results: Absorption curve-- The zirconium Neo-Thorin complex salt shows a maximum absorption at 580 mμ against Neo-Thorin (Figs. 1 and 2). Effect of pH-- The complex salt gives a maximum absorption at pH 1. 7 (Fig. 3). Effect of time and temperature-- Color absorption is stable for a period of 15 to 200 minutes after color development at room temperature. Heating over 40°C is harmful, because of the formation of a purple precipitation. Interference by several ions-- Cations UO(2)(2+) and Fe(3+) besides Th(4+), considerably interfer with color development. The absorption of 2000 μg U corresponds to that of 10 μg Zr (Fig. 4). However, interference by Fe(3+) becomes negligible if hydroxylamine hydrochloride is added. 2) As a result of the above conclusions, the following procedure is recommended: Procedure recommended-- A few ml of sample solution, 1 ml of 20% hydroxylamine hydrochloride and 1 ml of dilute acid, if necessary, are mixed and diluted to 9 ml. To this solution, 1 ml of 0.05% Neo-Thorin is added. The pH value of the final solution is 1.7. From 15 to 200 minutes after mixing, color absorption is measured at 575 mμ. In the range of 0 to 150 μg Zr per 10 ml, the color absorption of the complex salt obeys Beer's law (Fig. 5). 3) In demonstration, this method was applied to the determination of zirconium in a uranium mineral. Table 1 shows the zirconium content of beta-uranophane from Katamo Mine, Tottori-ken.
