چکیده انگلیسی
As a stable microporous material, de-aluminated Y zeolite has been used for the first time as an ozonation catalyst and showed remarkable activity for the removal of phenol and chemical oxygen demand (COD) in aqueous solution. The Y zeolite exhibited excellent repetitive-use performance even after continuous operation for 10 cycles. The ozone decomposition rate, influence of hydroxyl radical scavenger and influence of reaction temperature were investigated. The results indicate that Y zeolite accelerates the decomposition of ozone and the generation of hydroxyl radicals, consequently enhances the degradation of phenol and the removal of COD.
