摘要:
研究了超声/H2O2/CuO、超声/H2O2/N i2O3及超声/H2O2/MnO2非均相体系对苯酚的去除效果。以初始浓度25 mg/L的苯酚溶液为处理液,催化反应在带夹套的玻璃器中进行。在超声声强4.97 W/cm2、H2O2加入量300 mg/L、催化剂的加入量均为1 g/L、溶液温度30℃的处理条件下,3种体系中超声/H2O2/CuO组合对苯酚的去除效果最好。超声辐照240 m in时,单独超声、超声/H2O2、CuO/H2O2及超声/H2O2/CuO对苯酚的去除率分别为24.0%,53.3%,13.8%和89.5%,表明超声、H2O2与CuO具有协同作用。溶液温度从20℃上升到55℃时,3种组合下苯酚去除率均随温度升高有明显增大,表明温度较高时C6H5OH去除过程中催化作用起主要作用而非超声空化作用。
Abstract:
The deg radat ion of pheno l is invest igated in the presence of u ltrasound /H2O2 /CuO, u-l trasound /H2O2 /N i2O3 and ultrasound /H2O2 /MnO2 systems. The in it ia l concen trat ion of 25 mg /L phenol is se lected as model pollutant aqueous and the cata ly tic ox idation is carried out in a jacketed beaker. U nder the conditions o f ultrasound intensity 4. 97W /cm2, H2O2 in itial concentra tion 300 mg /L, cata lyst dosage 1 g /L and the temperature 30℃ , the h igher efficency o f pheno l degradation can be ach ieved in u ltrasound /H2O2 /CuO compared w ith other catalytic systems. The removal ratio of pheno l is 24. 0%, 53. 3%, 13. 8% and 89. 5% respectively correspond ing to u ltrasound, ultrasound /H2O2, CuO /H2O2 and ultrasound /H2O2 /CuO treatmen t systems w ith the u ltrasound irrad iat ion 240m in. It is indicated that u ltrasound, H2O2 and CuO have synerg ist ic effec.t When the temperature increases from 20 ℃ to 50 ℃ , the pheno l remova l ratio increases apparen tly under the three kinds of system s, therefore, the enhanced deg radat ion o f pheno l can be ascribed to catalytic effect instead o f u ltrason ic effect.
