摘要

Tc-HMDP和

Tc-HEDP溶液是在相应的螯合剂存在下，用过量SnCl

还原

TcO

制得。用标准I

液对SnCl

进行了剩余量电位滴定，确定了在pH~3的介质中，

Tc-HMDP和

Tc-HEDP中

Tc的氧化态均为+4。全部实验在N

气流中进行。

Tc-HMDP和

Tc-HEDP的紫外光谱表明：在用I

滴定的过程中，

Tc只处于一种氧化态+4；将它们放置在空气中，一小时后仍较稳定。

Abstract

Solutions of

Tc-HMDP and

Tc-HEDP were prepared by reducing

TcO

with excess SnC1

in presence of corresponding chelating agent. The quantity of unreacted SnCl

was analyzed with I

standard solution by potentiometric titration. It was found that

TcO

is reduced to the+4 state in either

Tc-HMDP or

Tc-HEDP at pH~3. The whole experiment was carried out under N

atmosphere. The UV spectrum of

Tc-HMDP or

Tc-HEDP shows that during the iodometric titration

Tc exists only in one oxidation state and

they are stable in air within 1h.
