本文讨论了多环芳硫烃 (PASH) 的声化学水处理，多环芳硫烃是石油工业废水中最常见的杂质之一。实验数据的最佳拟合似乎是在研究浓度范围内使用 Michaelis-Menton 模型确定的动力学参数。对于降解速率的初始增加，简单地认为体浓度增加得越多，界面区域的浓度增加得越多。这将通过米氏动力学来解释。还评估了水基质中有机化合物与苯并噻吩 (BT) 的混合物的影响。结果表明，BT 降解不受双酚 A (BPA) 存在的影响。最后，结果表明，在 BT 声化学降解中，超声波作用涉及氧化而不是热解过程。
This paper deals with the sonochemical water treatment of polycyclic aromatic sulfur hydrocarbons (PASHs), one of the most common impurities found in waste water coming from petroleum industry. The best fit of the experimental data appears to be the kinetic parameters determined using the Michaelis-Mentonmodel in the concentrations range of the study. For the initial increase in the degradation rates, it is simply considered that the more the bulk concentration increases, the more the concentration in the interfacial region increases. This will be explained by Michaelis-Menton kinetics. The influence of organic compounds in the water matrix as a mixture with Benzothiophene (BT) was also evaluated. The results indicated that BT degradation is unaffected by the presence of bisphenol A (BPA). Finally, the results indicated that ultrasonic action is involved in oxidation rather than pyrolitic processing in the BT sonochemical degradation.
