苯酚水溶液的光化学降解

Photochemical Degradation of Phenol in Aqueous Solution

研究了在无极紫外光的照射下苯酚的降解,探讨了苯酚水溶液的初始浓度、光照时间、溶液pH值、H2O2等因素对苯酚溶液降解的影响。结果表明：苯酚初始浓度为0.02mg.mL-1,pH值为4,光照时间为60min,加入6%H2O24mL时,苯酚水溶液的降解率最大。

Phenol degradation was investigated by electrodeless ultraviolet irradiation.The effect of initial concentration,PH and H2O2 on the degradation of phenol were studied.Results showed there are maximum rate of phenol degradation when the concentration of phenol was 0.02 mg mL-1,PH was 4,and illumination time was 60 min and adding 6% H2O2 4 ml.
