TLDR
In this paper, the synthesis and use of nitrogen-containing copolymers for anchoring Ru(II) and Rh(I) species is described, and the supported species are effective as catalysts for the decomposition of H 2 O 2 in aqueous medium at neutral pH.Abstract:
The synthesis and use of nitrogen-containing copolymers for anchoring Ru(II) and Rh(I) species is described. The supported species are effective as catalysts for the decomposition of H 2 O 2 in aqueous medium at neutral pH. The polymers as well as the supported catalysts have been characterised by physical and chemical methods. The effects of [H 2 O 2 ], catalyst loading and pH of the medium on the rate of decomposition have been studied. Suitable mechanisms have been proposed to account for the kinetics. Recycling efficiencies of the catalysts are found to be good.read more

Rapid decomplexation of Ni-EDTA by microwave-assisted Fenton reaction
TL;DR: In this article, the authors presented a comprehensive study about microwave-assisted Fenton process for the rapid decomplexation of Ni-EDTA, which showed that under the optimized reaction conditions, microwave irradiation promoted the cleavage of refractory linkages in metallic complexes, achieving 94.0% decomposition efficiency within 10 min reaction.
