Degradation of azo dye with dirhodium(II) caprolactamate as heterogeneous catalyst

The kinetics of the oxidative degradation of an azo dye Metanil Yellow (MY) was investigated in aqueous solution using dirhodium(II) caprolactamate, Rh(2)(cap)(4), as a catalyst in the presence of H(2)O(2) as oxidizing agent. The reaction process was followed by UV/Vis spectrophotometer. The decolor...
