Mineralization and efficiency in the homogeneous Fenton Orange G oxidation

Mostrar todas las versiones(2)

This study focuses on the homogeneous Fenton oxidation of the synthetic azo-dye Orange G as a model compound. The impact of initial TOC, hydrogen peroxide and catalyst concentrations and of temperature on mineralization and efficiency in the use of hydrogen peroxide is addressed. Dissolved oxygen co...
