| Research Abstract |
Results obtained in the present co-operative work are as follows.
Solute-solvent interaction in analytical chemical reactions. Solute-solvent interaction was evaluated through the studies on (1) solvent effects on the optical oxidation potentials of an ion, (2) solvent effects on the electrochemiluminescence, (3) reaction of hydroxide ion with electron acceptors in nonaqueous solvents, (4) ion association of metal perchlorates, and (5) complex formation between ion and solvent molecule.
Solute-slovent interaction and phase transfer reactions (solvent extraction). (1) Solvent extraction behavior of isopoly and heteropoly molybdates was systematized by applying solvatochromic parameters. (2) The solvatochromism was verified to be powerful for the explanation of solute-solvent interactions using macrocyclic tetramine nickel (II) complex. (3) Molybdophosphonate and molybdosulphate complexes were synthesized in a mixture of water and organic solvents, and their structures were determined. (4)

Extraction behavior of silvior (I) complexes of tetrathio ethers was explained based on their structure. (5) The capacity factor of metal complexes in reversed phase liquid chromatography was evaluated taking into account the liquid-liquid partition modal. (6) Chirality recognition was improved employing the adduct formation of Lewis bases with beta-diketone chelates in various solvents (7) Some novel reagents were proposed for selective solvent extraction of metals.
Electrochemical studies on solute-solvent interaction. Voltammetry for ion transfer at the liquid/liquid interface was applied to elucidate (1) principles of ion sensors and their applicabilities to biochemical species and (2) the interaction between the ion transfer and the electron transfer at an aqueous/organic solution interface. Basic data relative to solute-solvent and solvent-solvent interactions was accumulated through measurements of liquid junction potentials between different solvents.
New analytical methods based on solut-solvent interaction. (1) A method for the determination of proton concentration in paper was developed extracting proton into nonaqueous solvent. (2) Method for speciation of actinide ions was proposed based on their complexing ability in aqueous media. Less
