摘要
采用功率350W、40kHz超声波器和紫外光同时对水中的苯酚进行降解,考察了样品苯酚溶液的pH及浓度、加入6%H2O2和0.001mol/LFe2+(FeSO4)的量、超声波超声功率、紫外光照射的时间、紫外-超声联用降解的时间等条件的影响。结果表明,在苯酚的最佳降解条件(紫外-超声联用下作用60min,pH3～4,加入6%的H2O24mL和0.001mol/L的Fe2+(FeSO4)1.6mL)下,苯酚的降解率达91.8%,证明超声波诱导紫外光协同法是一种降解苯酚的有效方法。
The degeneration rate of phenol in aqueous solution by both ultrasonic wave and ultraviolet ray was studied. The effect factors including the ultrasonic wave power, time of the reaction, pH, and the amount of H2O2 and Fe^2＋ on the degeneration were investigated by the single factor method. Under the condition of adding 4mL 6% H2O2, 1.6mL 0.001mol/L Fe^2＋ （FeSO4）, ultraviolet irradiation time 60 min, pH 3 ～ 4, the best degeneration rate of 91.8% was achieved. Ultraviolet ray oxidation assisted with ultrasonic wave was proved to be an efficient method to degrade phenol.
