Cover Story: The accumulation of non-biodegradable organic compounds in the aquatic environment poses a serious threat to water and its biota. Here, we have investigated mono- and bimetallic formulations based on Co, Cu, Fe and Mn, for the Fenton-like treatment of three model organic dyes (methylene blue, rhodamine B and malachite green). These systems remove the target molecules with very high efficiency rates, under mild reaction conditions. The Mn-Fe catalyst results in the best formulation with an almost complete degradation of methylene blue and malachite green at pH 5 in 5 minutes and of rhodamine B at pH 3 in 30 minutes. The results suggest that these formulations can be proposed for the treatment of a broad range of liquid wastes containing complex and variable organic pollutants. View this paper
