| 抄録 | Methods and Results of Measurements:-- A stick of steel was driven into the ground down to one meter depth, and a narrow pipe of aluminum or brass, closed at the upper end, was inserted and the hole covered by a board and earth. (See Fig.3.) In Fig.2 the locations for the experiments are shown by x. Fig.1 gives the atmospheric temperatures at noon, October4-21,1955, when the experiments were carried out. About three hours after the above setting had been done, the gas in the hole was replaced by a bottle of water, and was collected, by driving sprayer for five minutes with apparatus as shown in Fig.5, in a can in which an autoradiographic plate was set. (See Fig.6.) The temperature in the hole was read by means of a maximum thermometer hung in the hole for ten minutes at one meter depth. Fig.7 shows the distribution of temperatures at one meter depth thus observed. Exactly twenty four hours after the above setting, the autoradiographic plate in the can (a quarter sized Fuji ET-2E plate, 15μ thick, for contact method) was developed. For developing, the plate was immersed in Ilford D-19 for fifteen minutes, then fixed with Fuji-fix for fifteen minutes, washed with running water for forty minutes, and dried. Then those autoradiographic plate was examined under the microscope of magnification ×280, to count the number of tracks of a-particles. The results obtained are shown in Fig.8. Underground Temperature Distribution:-- On the basis of the distribution of temperatures at one meter depth (Fig.7) and of other available boring data, the distribution of undergound temperatures is estimated as shown in Fig.9 (vertical section along the Misasa river). |

| タイトル（別表記） | THE CHANGE IN CONCENTRATION OF FERROUS IRON AND REDUCIBLE IRON, DISSOLVED IN SPRING WATER AT MISASA HOT SPRINGS, JAPAN, DURING PRESERVATION OF THE WATER SAMPLE IN A SEALED BOTTLE |

| 抄録 | The two sprigns called "Tanaka-no-Yu" and "Hisui-no-Yu" at Misasa Hot Springs, japan (Fig. 1), suitable for sampling the unpolluted water, the locations of which, are shown in Fig. 2, were chosen for this study. The o-phenanthroline method, details of which were discussed in the previous report by the author (Repts. Balneol. Lab. Okyama Univ., 17, 1, (1956)) was used for the determination of ferrous iron, ferrous iron + reducible iron, and ferrous iron + reducible iron + colloidally dispersed iron (to be referred to as "total irons" in this report). For comparison, the change in concentratin of iron dissolved in distilled water during preservation in a sealed bottle was observed, and the results obtained for the solutions with the pH values of 5.4 and 5.8 are illustrated in Fig.3 and Fig.5, rspectively. Both ferrous and reducible iron disappear within 5 minutes, when the pH of the solution is 6.4. The hydrogen ion concentration was thus seen to give a sensitive effects on the speed of diminution of ferrous and reducible iron dissolved in the distilled water. It should be noticed that no appreciable diminution was observed during the period from 60 min. to 120 min,. It is probable that the diminution of total iron is caused by the adsorption of colloidal iron hydroxides on the wall of glass bottle. The effects of charged anion (SO(4)(--)) on the change in concentration of iron during preservation was also investigated, but no appreciable effect was found. (Fig. 5 and Fig. 6). Fig.7, Fig.8, and Fig.9 show the change in concentration of iron during preservation of the spring water at "Tanaka-no-Yu". The content of iron in the spring water is about 0.3 mg/l, and its pH value is about 7.1. For the first 30 minutes, ferrous iron diminishes rapidly, the slope of the diminution curve being sharp and almost straight. Thereafter the slope becomes gentler, and, after an hour, the slope approaches nearly zero. On the other hand, ferrous iron dissolved in distilled water disappears in a moment at the same pH 7.1. Fig.10, Fig.11, and Fig.12 show the change in concentration of iron during preservation of the spring water at "Hisui-no-Yu". The content of iron in the spring water is about 1.0 mg/l, and its pH value is about 6.4. In this case, the diminution of ferrous iron is not remarkable, and only 20% of the initial quantity diminishes within 2 days. Whereas, in the case of distilled water, the diminution is very rapid at the same pH 6,4, and the ferrous iron disappears completely within 5 minutes. In Fig.13 the speed of diminution of iron in distilled water and that in spring water are compared. The difference here seen may probably be due either to that the ferrous iron in spring water is in a certain complex form not easily oxidizable, or to that the spring water contains some reducing substances. |

| 抄録 | Differential thermal investigation was made of amorphous hydrous ferric oxides, precipitated on neutralization of ferric chloride solution under different laboratory conditions, ranging from DOC to 85°C in temperature, and from 3 to 12 in pH. Each of the differential thermal curves obtained shows an endothermic peak due to the release of adsorbed water, followed by a exothermic peak due to crystallization of anhydrous ferric oxide to hematite. The temperature corresponding to the exothermic peak varies in the range from 240°C to 460°C accrding to the temperatures and pH values of the solution from which the hydrous ferric oxide is precipitated. |
