The formation and radical scavenging properties of ethylenediaminetetra-acetic acid N,N′-dioxide in aqueous m-chloroperbenzoic acid
Abstract
meta-Chloroperbenzoic acid rapidly oxidizes ethylenediaminetetra-acetic acid to the N,N′-dioxide which suppresses the CuII catalysed m-chloroperbenzoic acid oxidation of amaranth [trisodium 1-(4-sulpho-1-naphthylazo)-2-naphthol-3,6-disulphonate] by scavenging free radical chain propagating species.
