Abstract

Using the pulse radiolysis competition kinetic technique, OH radical rate constants with 12 metal DTPA complexes were determined in neutral aerated aqueous solutions. They are in the range of /1.3–5.9/×109 dm3 mol−1s−1. To a first approximation, the rate constant was found to decrease linearly with an increase in the field strength of the metal ion (q/r2).
