摘要

This paper reported the degradation of 4-CP wastewater by a novel photocatalysis oxidation system UV/Fe~(2+)/air system, in which air was used as a cheap oxidant that reacted with the excitation state of organics to form H_2O_2 under the UV light. The formed H_2O_2 reacted with the added ferrous ion to form Fenton reaction and led to the quick degradation of organic pollutants. It was found that 4-CP could be completely removed within 40 min. The degradation of 4-CP in the UV/Fe~(2+)/air system was superior to the conventional BV/Fenton system (the initial concentration of H_2O_2 was 22 mg centre dot L~(-1)). UV/Fe~(2+)/air is an effective and cheap method for treatment of the organics that can be excited by UV light.
