✦ Synopsis

The rate of reaction of (Fe(DTPA)) with Hz02 was investigated at various temperatures. The observed rate law is given by the expression.

The rate constants and the related thermodynamic parameters are calculated. Substitution controlled mechanisms are suggested to account for the formation of the violet peroxy intermediate. The results are compared with previously data for Fe EDTA complex.

Experimental

Diethylenetriaminepentaaceticacid (DTPA), Ferric chloride, and hydrogen peroxide were B.D.H., Analar grade.

The hydrogen peroxide decomposition kinetics were investigated for both "free" iron catalyst [Fe(II) and Fe(III)] and complexed iron catalyst [Fe(II) and Fe(III)] complexed with DTPA, EDTA, EGTA, and NTA as ligands (L). A kinetic model for free iron catalyst was derived assuming the formation of a r

## Abstract The heterocyclic compounds piperidine (Pip), piperazine (Pz), morpholine (Morph), and N‐methyl piperazine (N‐MPz) were used as ligands to form transition metal complexes with Ni(II), Cu(II), and Co(II) ions. These complexes were supported on Dowex‐50W resin so as to form new potential a
