Radical mechanism
WebRadical chain reactionshave three distinct phases: initiation, propagation, and termination. The initiation phasedescribes the step that initially creates a radical species. In most … WebThe aims of the present study were to (i) demonstrate unequivocally the formation of Fe aqIV in the reactions of Fe (II) and PMS or PDS in the absence of interfering chemicals, (ii) verify the generation of carbonate radical anions in the presence of bicarbonate in neutral solutions by investigating the kinetics and mechanisms of reactions of Fe …
