The catalyst was prepared by impregnation of copper (2.5\u00a0wt%) into pyrophyllite-type clay and characterized by X-ray diffraction, X-ray fluorescence, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and transmission electron microscopy. The optimum operation conditions for CWPO of phenol over Cu\/RC were determined by investigating the effects of pH, temperature, catalyst amount, and hydrogen peroxide concentration. Stability of the Cu\/RC catalyst and toxicity of treated solution were studied, by measuring the copper concentration leached out from the catalyst and the inhibition of\u00a0Vibrio fischeri\u00a0bacteria bioluminescence, respectively. The probable degradation mechanism of phenol over Cu\/RC was considered by HPLC analysis. The obtained results showed that Cu\/RC achieved highest activity (total phenol degradation and 80% TOC reduction) and detoxification with remarkable low copper leaching concentration (0.006\u00a0mg,L\u22121)mg,L\u22121)\u00a0at optimized conditions (pH\u00a0==\u00a03,\u00a0T=50\u2218T=50\u2218C, 2\u00a0g,L\u22121g,L\u22121\u00a0catalyst amount, 50\u00a0mg\u00a0L\u22121L\u22121phenol concentration and 7.45\u00a0mmol,L\u22121mmol,L\u22121\u00a0hydrogen peroxide concentration during 4\u00a0h). Meanwhile, few intermediates with low concentration were observed by the HPLC analysis for the CWPO of phenol. The Cu\/RC catalyst showed a good activity after five successive runs (88% of degradation and 73% mineralization) at optimized conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The copper-impregnated pyrophyllite (Cu\/RC) was prepared and used as catalyst in catalytic wet peroxide oxidation (CWPO) of phenol.
