The reductive degradation of Orange II in aqueous solution by zero‐valent iron was investigated. The degradation of Orange II followed pseudo‐first‐order kinetics at various pH values and initial Orange II levels, but the formation of sodium sulfanilate, a major reductive product of Orange II, followed zero‐order kinetics.
