| Author | Ashizawa, Takashi| |
| Abstract | The principle of this method is to combine the metals with organic reagents, then extract them with non-polar solvents, and determine them by making chromatograph with adequate adsorbents. Dithizone is used to determine Hg, Cd, Bi, Ag, Cu, Zn, Ni, Co, Tl, Pb, Pd and its isotopes, Pt group, Au, etc. Diphenylcarbazone is applicable to determine Hg, Cu, Zn, Ni, etc. Xanthate is useful to determine Mo, Cu, Ni, Co, etc. α-orβ- Nitrosoβ- orα-naphthol is used to determine Fe, Co, earth acids etc. Diethyldithiocarbamate is used to determine Mo, Cu, Ni, Co, Fe, etc. Oxine series are useful to determine Cu, Ni, Fe, V, rare earth etc. α-indolcarbonic acid is applied to determine Fe, Co, rare earth etc. Acethyl acetone is used to determine Th, Fe, etc. Some other organic reagents were used moreover. There are some elements of which necessary condition for quantitative determination is still not decided or the order of adsorption is indefmite. As adsorbents alkaline, neutral or acid alumina, diatom earth and aluminate, magnesium carbonate, calcium carbonate, urea formaline resin, heulandite, mordenite, desmine, chabazite etc· were used. With this method the author tryed severd determinations on rocks, minerals, mineral springs, organisms etc. The contento; of Cu, Zn, Ni and Co in rocks were 0.007, 0.008, 0.002 and 0.004% respectively. Cobalt content proved to be more than that of nickel. The mercury content of rocks was proved to be 10 times more to Clarke number, bismuth and cadmium content as same as or less than Clarke number. Silver in plants, soil and mineral waters, platinum in serpentine; mercury, cadmium, bismuth etc in mineral waters, trace heavy metals in organism, etc were determined. Radium B and Thorium B in hot spring waters were used as tracer. As organic solvents methyl-, ethyl-, butyl-, amy1-, octyl alcohol, dioxan, benzol, toluene, xylol, petroleum ether, ether, ethylacetate, chloloform, carbon tetrachloride, carbon disulfide etc were applied. |

| Author | Ashizawa, Takashi| |
| Abstract | Flocculation value of 24 mineral waters was measured with colloidal solution of iron hydroxide. There exists a negative correlation (r=-0.72, Fo=(r(2)(N-2))/(1-r(2)) =21.6 >F=8.10 n1=1 n2=20 α=0.01) between the logarithms of sulfate ion concentration of the mineral waters and their Flocculation value. |

| Title Alternative | MICROANALYSIS OF ALUMINUM AND IRON. |
| FullText URL | 005_076_081.pdf |
| Author | Ashizawa, Takashi| |
| Abstract | アルミニウムと鉄の満足な分離定量法は,現在知られていない.微量のアルミニウムの定量法としては,各種色素のレーキ生成による比色法もあるが,最も優れた方法はオキシン法である.鉄定量は専ら各種の比色法又は容量法に依っているが,微量の場合は実際にはロダン法が用いられている.食塩泉に存在 する様な,1l中数mg以下の,アルミニウム及び鉄の実用的な分析方法を確立する必要を感じ,従来法を改良し,満足な結果に到達した.鉄はロダン法又はサリチル酸法,アルミニウムはヘマトキシリン,又はアルミノン,オキシン法が用いられた.本法の特徴は,鉄をロダン錯塩としてアミルアルコールで完全に抽出し定量し,残液でアルミニウムをアルミノン,オキシン等で定量する一貫した方法であることにある.現在のアルミノン法は鉄の妨害のために実用化されていない.鉄の定量の際の弗素の影響は余り関心を持たれていないが,温泉水には著量の弗素を含むものがある.それでこの妨害を避けて,サリチル酸法に硝酸トリウムを用い,正確に,比色する方法を考案した. |

| Title Alternative | RELATION BETWEEN THE MOTTLED TOOTH, STRUMA AND FLUORINE CONTENT OF DRINKING WATER INVESTIGATION ON BOYS AND GIRLSLIVIING IN YOSIOKA HOT SPRING AND ITS VICINITY,TOTTORI PREFECTURE, JAPAN |
| FullText URL | 005_064_075.pdf |
| Author | Onda, Sakue| |
| Abstract | In order to stady the relation between the mottled tooth, struma and fluorine content of drinking water, the author investigated the teeth and thyroid glands of school-boys and girls living in Yoshioka Hot Spring and its vicinity, Tottori Plefectue. Yoshioka Hot Spring is a simple thermal with high fluorine content (max. 5mg. per liter). The incidence of the mottled tooth was 51.5 per cent in average. A close relationship was observed between the morbidity of the mottled tooth and high fluorine content of drinking water. But the author noticed also the occurrence of the mottled tooth among the school-children living in the regions where the fluorine content of drinking water proved to be even less than o.1ppm., and the author emphasizes the possibility of the causal factors other tham fluoline. The palpability of thyroid gland was 78.4 per cent in average, but no significant relation was recognized between the struma and fluorine. Between the mottled tooth and struma, no relation was proved as significant, too. |

| Title Alternative | STUDIES OF THE RADIOACTIVE SPRINGS (XXIX) THE EFFECT OF FREQUENT THERMAL BATH ON BLOOD CATALASE |
| FullText URL | 005_059_063.pdf |
| Author | Morinaga, Hiroshi| |
| Abstract | The author investigated the effect of frequent thermal bath on blood catalase in healthy persons, liver injured patients and rabbits. The blood catalase level of rabbits tends to increrease after a radioative thermal bath at a temperature of 42°-43℃ in " YAMADA-KU KYODO-YU " . but it tends to decrease after a thermal bath in the Labolatory, which Radon content is about one tenth of the former, namely 40-70×10(-10) Curie units per liter. By the repeated thermal baths of daily three times the blood catalase level of rabbit tends to fall lower after each bath. In healthy persons no remarkable change was shown in the initial blood catalase level by the frequent thermal baths of daily three times at 42°-43℃for 5 minutes. But in liver injured patients a gradual fall of initial level and a slow recovery were seen after each thermal bath. |

| Title Alternative | STUDIES ON VITRIOL SPRINGS,(7) IN-VITRO EFFECT OF VIIRIOl WATERS ON OXIDOREDUCTASE. |
| FullText URL | 005_055_056.pdf |
| Author | Oshima, Yoshio| |
| Abstract | Fujino and Yanahara spring waters were used. The latter, is the strongest copper spring in Japan. Iron ion in Fujino mineral water is mainly ferric and in Yanahara mineral water mainly ferrous. Yanahara spring water promotes the action of oxidoreductase in milk and liver extract. It also promotes the action of succinic dehydrase in albino rat muscle. And this promoting action of spring water is inhibited by cyanide. Fujino is less active than Yanahara and Mitsuishi proved to be almost inactive. |

| Title Alternative | STUDIES ON THE VITRIOL SPRINGS. (6) |
| FullText URL | 005_051_054.pdf |
| Author | Ashizawa, Takashi| |
| Abstract | a) Colorimetoric determnation of the minute amount of antimony and antimony contend of Yanahara Hot Spring. To 5cc of sample soln., not containing the second family other than antimony. add 0.2 cc of 10% polyvinyl alcohol aqueous solution. Adjast HCI eoncentration to approximately I. N. Add I cc of hydrogene sulfide solution and sbake. Then measure the reruting yellow or orange color by photometer. Antimony content of Yanahara Hot Spring was 0.1±0.03 g per liter by the above mentioned method. b) Quantitative determination of the free mineral acid. Precipitate iron and aluminium as complex fluorine salts and change the sulfate ion into alkali sulfate, so that it can not liberate free acid. Then titrate with alkali using phenol red as an indicator. c) Iron and coprer in thermal waters and minerals of Yanahara Hot Spring. Ferous ion content of Yanahara Hot Spring (60℃) was 14.6g per liter and its copper content was 0.44g per liter. both being the highest record in Japan. A green and a bluish green minerals ware found, crystalyzed near the Hot Sprig. The latter was apisanite (Cu(0.25) Fe(0.75) S0(4・8.8) H(2)O) and the former proved to be a pure melanterite (Fe S0(4).7H(2)O). d) A modified method to detect sulfides of the second family. Using zinc-amalgam the author succeeded to avoid the liberation of sulphur and to detect the yellowish or orange colored sulfides, such as ausenic, antimony or tin sulfide. e) Paper chromatography applied to the analysis of heavy metals in vitriol waters. 4 kinds of vitiol waters were investigated. Paper chromatography proved to be excellent in detecting the metals of the second family, such as tin, antimony, and ansenic. |
