リン酸トリブチルによるユウロピウムの溶媒抽出・逆抽出過程を、微小油滴の顕微蛍光法測定から速度論的に解析した。速度定数の硝酸,硝酸イオン,リン酸トリブチル濃度依存性から、抽出は油水界面で硝酸イオン2つを伴うユウロピウム移動に支配されること、逆抽出速度とこれら濃度との定量的関係を明らかにした。

The solvent extraction / back-extraction process of europium with tributyl phosphate was kinetically analyzed from the microfluorescence measurement of micro organic droplets. From the rate constant dependence on nitric acid, nitrate ion, and tributyl phosphate concentrations, it was clarified that extraction is governed by the movement of europium with two nitrate ions at the organic-aqueous interface, and the quantitative relationship between the inverse extraction rate and these concentrations.
