| 摘 要： | 研究了初始浓度为4mg/L的腐植酸溶液在频率为1．1MHz超声波作用下的降解规律。首先测定了该溶液在190～320nm的吸收光谱，然后测定了降解过程中不同的pH条件下TOC的削减情况，并分析了降解过程的自由基氧化历程。

| Abstract: | The changes of ultraviolet spectra in the range of 190 - 320 nm of the humic acid sonochemical degradation process were studied. The experimental results show the ultrasound has a high degradability to humic acid. The TOC removal rates in different pH ranges were 8% - 15%. With the increase of pH value, the TOC removal rate is higher accordingly. |
