Cd7Th, Zn7Th, Bi7Th, Hg7Th and Pb7Th have been prepared, and the kinet
ics of reactions of these five MTs with varied ligands were discussed.
From the observed pseudo-first order rate constants, two possible mec
hanism were determined respectively. The reason of induction behaviors
of varied heavy metal ions in vivo also was suggested on the basis of
above results.
