Wet peroxide oxidation of paracetamol using Fe/Co-pillared clay catalysts prepared from natural clays
| Resumo: | This work deals with the catalytic wet peroxide oxidation of paracetamol, considered as model emerging pollutant, using as catalysts low-cost materials based on pillared clays prepared from natural clays. Pillared clays were prepared successfully through a pillaring solution containing cobalt and iron. The prepared clays allow to remove completely the pollutant after 8 h of reaction at 80 ºC, initial pH 3.5, Ccatalyst = 2.5 g L-1, Cpollutant = 100 mg L-1 and CH2O2 = 472 mg L-1, whereas in the non-catalytic run only 20% removal of pollutant was obtained after 24 h at the same operating conditions. |
