Abstract

The decomposition of EDTA and DTPA was studied in simulated chlorine dioxide bleaching condition Under the investigated conditions EDTA and DTPA decomposed readily. Accordingly, feeding the chelating agents to the first chlorine dioxide stages (D0) should be reconsidered, when successful metal removal is desired. On the other hand, chlorine dioxide water may be utilized to degrade the chelating agents.
