Ferroin in dyes degradation by Fenton-like process: a chemical waste recycling perspective

open access: yesWater Science and Technology, 2021
Published literature describes the formation of the Fe (II)–phenanthroline complex (ferroin) as a stop way for Fenton processes, reducing radical yield. By contrast, this study presents evidence that ferroin can be activated by UVA in mildly acidic media
