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) THE FLUORINE CONTENT OF WATERS AT MISASA HOT SPRINGS

抄録 The fluorine content of certain thermal and ground waters in this district was determined colorimetrically by the use of Neo-Thorin. The temperature and the chloride, bicarbonate and calcium content of the same waters were also determined. It was found that fluorine content ranged from 0.6mg/l to 9.1mg/l in the thermal waters and was less than 0.6mg/l in the ground waters. The positive and linear correlation between the fluorine content and the Cl(-), HC0(3)(-), and Ca(2+) content was considered to be the outstanding characteristic of the thermal waters of this area. From these facts, it is concluded that the fluorine in the waters at Misasa Hot Springs is originally introduced from the same source as the thermal waters.

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.
