摘要: 以四环素(TC)为研究对象,探讨了超声功率、初始浓度、pH值以及超声协同H2O2、TiO2、Na2CO3等组合工艺对超声降解TC效率的影响.实验结果表明,超声可有效降解水中低浓度的TC,尤其在碱性条件下,超声降解更为显著.加入H2O2、TiO2和Na2CO3在一定程度上都可以促进水中TC的降解.依据量化计算以及LC-MS测定结果,探讨了TC的超声降解机理,揭示超声降解水中TC主要是基于·OH自由基的氧化过程.

Abstract: The effects of ultrasonic power, initial concentrations, solution pH values and additives (H2O2, TiO2 and Na2CO3) on the degradation efficiencies of TC by ultrasound (US) were studied. Experimental results show that low-concentration TC was effectively removed by ultrasonic irradiation in aqueous solution. The presence of OH- remarkably enhanced TC removal efficiencies. In addition, H2O2, TiO2 and Na2CO3 also promoted ultrasonic induced degradation of TC to some extent. TC ultrasonic degradation mechanism was mainly ascribed to 稯H oxidation, which was supported by the results of quantum chemical calculations and LC-MS measurement.
