The Anodic Oxidation Of Methyliminodiacetic Acid (MIDA)on Pt In Perchloric Acid Media
The oxidation of methyliminodiacetic acid (MIDA) on platinized-platinum was studied potentiostatically in perchloric acid media at 25° C. Steady-state polarization curves were obtained for MIDA concentrations of 3.0·10-3M to 7.0.10-2 M in 0.05 M to 2.5 M perchloric acid. Carbon dioxide was produced and product analyses showed that the electrochemical oxidative decarboxylation involved only one carboxymethylene group. While the rates of decarboxylation were only slightly affected by changes in the concentration of MIDA over the range studied, they showed a pronounced dependence on pH. A series of cyclic voltammetry measurements did not indicate the formation of stable intermediates. A reaction sequence, which is correlated with metal-ion oxidation of MIDA in perchloric acid, is proposed. © by Akademische Verlagsgesellschaft, Wiesbaden 1975
