ガラス固化体製造時の負担軽減のため高レベル廃液からの分離を検討しているパラジウム(Pd),モリブデン(Mo)及びルテニウム(Ru)について、硝酸溶液中における溶存状態を、分光学的手法を用いて調査した。Pd, Moについては各種錯体種の錯形成定数及びモル吸光係数のデータを得た。Ruについては経時変化が顕著であり、この速度は硝酸濃度に依存した。

Speciation of palladium, molybdenum and ruthenium in nitric acid solutions was studied through spectrophotometric method to obtain basic data for the development of separation process for these elements from high-level liquid waste. Absorption spectra of various solutions of Pd and Mo gave data on complex formation constants and molar absorption coefficients for some chemical species. As for nitric acid solution of Ru, slow rate of change in absorption spectra was observed, which depends on the nitric acid concentration.
