Abstract

Reaction mechanism of base hydrolysis of halobis/8-quinolinolato/oxotechnetium (V) /TcOX (ox)2′ X=Cl and Br/ was investigated by means of solvent extraction and spectrophotometric methods. Furthermore, distribution coefficients of tris/acetylacetonato/technetium/III/, dichlorobis/8-quinolinolato/technetium/IV/ and TcOX/ox/2 between chloroform and aqueous solutions were determined. In an alkaline solution, TcOX/ox/2 decomposed to pertechnetate as a final product. On the basis of the established base hydrolysis, the respective rate constants were determined.
