Degradation of Furfural by UV/O3 Technology

Furfural in aqueous solution was treated by UV/O3 method.The results show that the removal rate of furfural is severely enhanced and the synergism phenomenon appears when ultraviolet and ozone are present together.The influences of experimental parameters such as pH,the intensity of light and the negative-positive ions on furfural degradation were investigated.The results indicate that furfural（300 mg/L） is almost completely degraded after 3 h under the optimum conditions.The intermediate in the furfural degradation was characterized by GC-MS and IR spectrum and the degradation mechanism of furfural by UV/O3 technology was proposed.
