本研究では、水試料中の溶存Feの酸化状態に関する正確な情報を取得する必要がある。この目的のためにFe(II)-フェナントロリン（phen）錯生成系を適用した固相分光法をこれまで用いてきたが、同法の正確さを評価するために、試料溶液中の溶存Fe分析を行う過程で生じる可能性があるFeの酸化状態の変化について検討した。
実試料中においてFeは有機錯体として存在している可能性が高い。したがってモデル配位子としてエチレンジアミン四酢酸（EDTA）を共存させた場合のFe-phen錯生成系で、溶存Feの酸化状態について検討した。Fe(II)-phen錯生成における至適pHであるpH 5において、EDTA濃度が1.0×10-5 mol dm-3以下ではFe(II)-phen錯生成が完全に進行し、溶存酸素の存在下でもFe(III)に酸化されることなく錯体は安定に存在することが確認できた。しかしながらpHを海水とほぼ同じ8としたところ、わずか3分程度で95 %以上のFe(II)が溶存酸素によってFe(III)に酸化された。またFeの酸化が生じたこの溶液にphenを添加すると、溶存酸素によって酸化されたFe(III)からFe(II)への還元が徐々に起こり、1時間後で10 ％程度、4時間後では25 %程度のFe(II)が検出された。本研究では、試料採水時にCO2 を溶解させてpH を6 以下に下げた後に酸処理した試料を定量に供し、さらに定量操作は0.5時間程度で終了するが、上述の結果よりこの試料採取法と定量法で、Feの酸化状態を変化させることなく正確さの高い定量が行えていることが確認された。

Super-concentrated electrolyte solutions and solvate ionic liquids exhibit ionic conduction and electrode reactions not found in conventional dilute electrolyte solutions. They are hardly explained in the framework of conventional electrolyte solution theory based on continuous dielectric models such as Walden's law and Stokes' law. In addition to macroscopic thermodynamics and transport theory, we approached from structure and dynamics at the molecular level in order to reveal the ion transport and electrode reaction in super-concentrated electrolyte solutions and solvate ionic liquids.

One of the causes of Isoyake, sea desert, around the Japan coast is attributed to the decline in the supply of the dissolved iron from river. Fe(III) complexes of humic substances in the river water should be coagulated when the river water is mixed with seawater. Our hypothesis is that Fe(II) is mainly supplied to the sea during storm runoff and forms dissolved Fe(III)-organic complexes in the presence of O2. To prove this hypothesis, on-site analysis method was established using solid-phase spectrophotometry to measure the low concentration of Fe(II). The sample collection method was also established by dissolving CO2 in sample solution to decrease pH and the dissolved O2 concentration and then by keeping pH at 2 within 1 hr after the sample collection. The bottom water of high Fe(II) concentration in the river was present in the local reduction environment under anoxic conditions. It was found that the Fe(II) flux at flood runoff was one hundred times more than that at base flow.

鍾乳石とトゥファから環境情報を取り出すための手法を確立することを目的として、次の項目について検討を行い、それぞれの項目に関して以下の成果を得ることができた。
1.秋吉台の鍾乳石試料を用いて秋吉台が草原化した時期を明らかにする。
(1)現在も成長を続ける石筍の絶対年代見積りには、今回確立した顕微蛍光法による年縞の計測が有効であった。
(2)鍾乳石およびトゥファ中で蛍光を発する成分のキャラクタリゼーションを蛍光スペクトル分析により行い、これらの蛍光にはいずれもフルボ酸の寄与が大きいことを明らかにした。
(3)草原地域の洞窟の石筍の炭素同位体比の変動を追跡することで、約400年前から継続的な"山焼き"が行われるようになったことがわかった。
2.平尾台のトゥファを用いて、過去130年間の北九州工業地帯の大気汚染変遷を明らかにする。
(1)顕微分光法を用いて得られた絶対年代のクロスチェックのために、鍵層を見出すことを試みた。長崎原爆と1960年台初頭の大気圏内核実験に起因する^<137>Csの高濃度部分をトゥファ中で見出すことができた。
(2)鍾乳石およびトゥファ中の硫酸イオンがイオン交換反応で共沈することを国内および台湾の試料を用いて明らかにした。
(3)明治以降の北九州工業地帯の大気汚染変遷をトゥファ中の硫酸イオン濃度から読み取ることができた。
3.大分県稲積水中鍾乳洞の水没鍾乳石から阿蘇火山の大規模活動と鍾乳洞発達史との関連を明らかにする。
(1)カナダMcMaster大でU-Th法による絶対年代測定を行った大分県稲積水中鍾乳洞の水没鍾乳石について、再検討を行った。水没の原因はAso-4火砕流による谷の埋没にあると考えられていたが、見積もられた絶対年代は17万年前となり、Aso-1とAso-2の間に成長したことが明らかとなった。鍾乳石中の厚さ1mm程度の粘土層の枚数は鍾乳石の水没の回数と一致するものと考えられる。

Studies were done using commercially available linear dextran and crosslinked polyols such as Sephadex gel, QAE-Sephadex anion-exchange dextran gel, and Amberlite IRA-743, a boron-selective resin which has a functional group of N-methylglucamine. Together with the distribution measurements of borate on the crosslinked polymers, ^<11>B NMR spectroscopy was employed to elucidate the nature of the complex formation of borate with the polyols. The results obtained were as follows : (1) for the adsorption of borate on a crosslinked dextran. DELTAH values were comparable to those for the complex formation ob borate with monosaccharides and the borate concentration dependence of boron adsorption is a characteristic property of the crosslinked dextran. (2) Well-resolved ^<11>B NMR spectra for the solid gel as well as for a dextran solution were observed. In the dextran system, borate complexes both with alpha, beta-diols and alpha, gamma-diols of glucopyranoside residues were present. This crosslinking of dextran caused the effective concentration of alpha, beta-diol moieties in the crosslinked polymer ligand to become higher than the practical concentrarion, so that the 1 : 2 complexation became more fovorable accoding to the increase in the degree of crosslinking. (3) The borate concentration dependence of boron adsorption on crosslinked dextran gel may be caused by the exclusion of borate anions from the gel phase due to electrostatic repulsion between borate and the fixed anion sites of borate complexes in the gel phase. The stability constant of each complex is similar to that for the Sephadex system : the presence of the fixed cation group in the QAE-Sephadex gel phase did not promote the boron adsorption. (4) The pH of the N-methylglucamine resin phase remains constant in the range of 10 to 11 when the equilibrated bulk solution is pH 6-11. The strong adsorbability of borate on the resin in a wide pH range is due to this phenomenon. From the ^<11>B MAS-NMR measurements, the active species in the resin were proved to be borate complexes of alpha, beta-diols in the functional groups.
On the basis of the results obtained, a novel boron-selective polymer was synthesized by introducing tris (hydroxymethyl) groups into chloromethylated polystirene. The properties of this resin are now being investigated.

On the basis of the topographic divide and the existence of two groundwater systems, the catchment basins in the Akiyoshi-dai Plateau limestone area(Yamaguchi Prefecture, Western Japan)are divided into six areas:Hirotani(where Akiyoshi-do Cave is located),Kanoide,Kuroiwa,Ono,Narutaki and Sowa. In this limestone area,groundwater flows out from 4 springs and 5 caves at the foot of the plateau. The origin of the dissolved components in the groundwater was estimated by using the self-consistent least squares method proposed by Tsurumi(1982). The contents of the dissolved components for all spring waters could be explained by the mixing of only three sources: one rich in limestone components,another in non-carbonate rock components,and the other in calcium sulfate probably originating from fallout and sulfur-oxidation in the soil in the plateau.
With an area of 18.5km^2, the catchment basin of Akiyoshi-do Cave occupies about half of the Akiyoshi-dai Plateau, where the annual mean precipitation is 1,974mm,and the average run-off from Akiyoshi-do Cave is estimated to be 955 mm. The calcium concentration of the baseflow showed seasonal fluctuations,and followed changes in the soil's CO_2 partial pressure. Measured soil CO_2 in the humus soil varied from 0.15% at a soil temperature of 7.2ﾟC to1.7% at 19.0 ﾟC, whereas in the meadows which cover most of the area,it ranged from 0.08% at 3.8ﾟC to 1.2% at 20.8ﾟC. The calcium concentration in groundwater issuing from the Akiyoshi-dai Plateau is controlled by the water-limestone dissolution equilibrium,under open system conditions depending on the meadow's soil CO_2 contents. A yearly average of 2,100tons of limestone was dissolved in groundwater issuing from Akiyoshi-do Cave,about 5% of which,of 110tons, was dissolved by acidic deposition.
Ion-exchanger phase absorptiometry was applied to the flow analysis of trace amounts of copper. This method permitted a highly sensitive,selective determination of copper in karst groundwater samples without any preconcentration. By measuring the copper concentration response in the water after a storm,the infiltration rate of rain water from the soil zone to the underground river of this karst groundwater system could be evaluated to be about 10-20m day^<-1>. On the other hand,the tritium concentration response suggested that the faily long residence groundwater(about 40years)entered the groundwater system after a big storm.
