Study of the Interaction Between Technetium and Tetrahydroxy-1,4-Quinone

Abstract

Technetium/Technetium in vegetation/Tetrahydroxy-1,4-quinone/Technetium complexet SummaryInteractions between technetium and tetrahydroxy-1,4-quinone (THQ) in presence and absence of a reducing agent (SnCl,) were studied. It was found that in absence of the reducing agent THQ was oxidized by Tc(VII) and complex formation took place between reduced technetium and the oxidized reagent. In the presence of Sn(II) ions, reduction of THQ was observed, technetium acting as a catalyst. As a consequence of these studies a catalytic method for technetium determination was developed and applied to the determination of the element in vegetation.

Preparation of a Succinimidedioxime-Technetium Complex Using Sn(ll) as Reductant. Potentiometric- Photometric Study

“…However, Information about mechanisms of complex formation is scarce. For this reason we have developed a program to study reactions of technetium in presence of a great number of ligands [6][7][8][9][10][11][12][13][14], with the aim to find information about the different reactions and mechanisms of complex formation. In this paper the reaction between technetium and succinimidedioxime is described, a ligand containing oxygen and nitrogen as heteroatoms and the results are compared with those obtained when a-benzoinoxime is üsed as reagent.…”
