| Title Alternative | Direct colorimetric and volumetric determination of calcium with new reagent |
| FullText URL | rbl_003_039_042.pdf |
| Author | Ashizawa, Takashi| |
| Abstract | The anthor found that azocal-A reacts only with calcium, and devised a direct colorimetric, and a direct titration method for calcium determination using azocal-A as an indicator, and obtained a satisfactory result. Accuracy : detectable amount in NaOH……0.28 γ, of Ca ; detectable amount in NH(4)OH……2 γ, of Ca. Sensibility……1 : 125,000 & 1 : 17,500 respectively. Interfering substances : Fe, U, Ni, Co, Hg, Ag, citrate, tartarate, oxalate, large amount of NH(4) salts, Sr, Mg. Not interfering subst. : Ba, F, acetate and silicate. Reagents : Saturated soln. of azocal-A in weak NaOH soln.. Spot test procedure : Place a drop of the acid or neutral test soln. upon white spot plate, add 1 drop of azocal-A soln., and mix them. If a yellow color appears, calcium is present. Colorimetric method: Transfer water sample containg not more than 0.05 mg of calcium, and not more than 5 mg of Fe, Mn, Mg, etc. to a 20 cc colorimetric tube, add 0.5-1 cc of azocal-A soln. and 0.5 cc of 6N-NaOH soln.. Allow it to stand for 10 minutes. Then compare the resulted yellow color with standard Ca soln. prepared similarly and simultaneously. Volumetric method : Amount determinable : 0.1 g of calcium. Transfer 40 cc of sample containg 5-100 mg to a 100 cc Erlenmeyer's flask, add 0.5 cc of 6N-HCl, add azocal-A to the amount of pink color as caused by methyl orange in acid soln.. Make alkaline with 1 cc of 6N-NaOH. Add 10 cc alcohol to every 40 cc of the sample solution. Then its color turns to yellow. Titrate with 0.1 N oxalate soln.. 1.0 cc of 0.1 N oxalate soln. is equivalent to 2.0 mg of Ca. Absorption band of the acid soln. at 4900 A, alkaline soln. at 5000 A, Ca-compound at 4300 A. The azocal-A is o-carboxy-benzol-azo-2-naphtol 3, 6-disulfonic acid prepared from anthranilic acid and R-salt. |

| Title Alternative | Studies of the radio-active springs. XXV The effect of Thoron spring bath on Rotter's reaction |
| FullText URL | rbl_003_018_020.pdf |
| Author | Oshima, Yoshio| |
| Abstract | In the preliminary papers the author reported that the Thoron in thermal water passes throngh the skin and stimulates the subcutaneous connective tissue cells. Sotozono proved that the reduced ascorbic acid content in the blood increases after the Radonspring bath. Before and after thermal bath the author measured the time necessary for the complete decoloration of intradermally injected dichlorphenol-indophenol solution. Compared with the plain water bath at a same temperature, the Thoron spring bath seems to have a tendency to reduce the time necessary for the decoloration. |

| Title Alternative | STUDIES ON THE AGING OF THE MINERAL WATERS (Ill) VARIATION OF SILICATE IN THEMINERAL WATERS |
| FullText URL | pitsr_012_006_010.pdf |
| Author | Sugihara, Takeshi| |
| Abstract | When silicate content is determined by the colorimetric method, the silicate content in the mineral waters and sodium silcate solution decreases in addition of ammonium hydroxide and sodium carbonate respectively, and moreover after addition of aluminium ion in the samples, when aluminium hydroxide is precipitated from ammonium hydroxide solution, total silicates in various forms are coprecipitated with it. The silicate content in the mineral waters that are kept in concentrations of 0.1～0.4 normality of sodium hydroxide showed special variations with times. |

| Title Alternative | STUDIES ON THE CHLORIDE AND SULFATE CONTENT OF WELL WATERS AND THE AMOUNTS OF CHLORIDE A;\lD SULFATE FIXED TO THE SOIL IN THE MINERAL SPRING DISTRICTS (VIII) MATSUZAKI, TOGO AND ASOZU HOT SPRINGS, TOTTORI PREFECTURE, JAPAN |
| FullText URL | 012_001_005.pdf |
| Author | Kimura, Kenjiro| Umemoto, Shunji| |
| Abstract | In Matsuzaki, Togo and Asozu Hot Springs which issue around the Pond Togo, the chloride and sulfate content and water temperatures of well waters and the amount of chloride and sufate fixed to the soil were determined with samples collected from various parts of the thermal spring districts and its neighborhood. The chloride and sulfate content and water temperatures of the well water samples collected from the thermal spring districts were higher than those from its neighbourhood, but for the amounts of chloride and sulfate fixed to the soil, no difference was detected. As the existence of other sources which would supply the chloride, sulfate and heat to the water is not expected, the difference in the chloride and sulfate content and water temperatures of well waters, between the samples collected from the thermal spring districts and its neighbourhood, seems to be due to the effects of thermal springs. |
