Effect of contact time, catalyst mass, and 4-nitrophenol concentration on the degradation yield via catalytic oxidation. Experimental conditions: (a) 0.2 g of catalyst, 11 mg/L of 4-nitrophenol concentration, pH 7, and 27°C, (b) 11 mg/L of 4-nitrophenol concentration, pH 7, and 27°C, (c) 0.2 g of catalyst, pH 7, and 27°C.
