Abstract

In this study, gas–liquid discharge plasma excited by nanosecond pulsed voltage is used to efficiently remove tiamulin (TIA) from water. The discharge produces a large number of reactive species (H2O2, OH radicals, NO3−, etc.) that can attack the TIA molecules. The effects of peak pulse voltage, initial TIA concentration, gas composition, and the addition of ferrous sulfate and persulfate on TIA removal were mainly investigated. The results showed that the oxygen plasma could approach 100% removal within 30 min of treatment time. The addition of the catalyst increased the TIA removal efficiency by approximately 15% during the 10‐min discharge treatment time. The toxicity of 12 intermediates was analyzed and the degradation mechanism of TIA was investigated.

纳秒脉冲气液放电水下去除替莫林的研究

在这项研究中，利用纳秒脉冲电压激发的气液放电等离子体可有效去除水中的替姆林（TIA）。放电产生的大量活性物种（H2O2、OH 自由基、NO3- 等）可攻击 TIA 分子。主要研究了峰值脉冲电压、TIA 初始浓度、气体成分以及硫酸亚铁和过硫酸盐的添加对去除 TIA 的影响。结果表明，氧等离子体可在 30 分钟的处理时间内达到 100% 的去除率。在 10 分钟的放电处理时间内，催化剂的加入使 TIA 的去除率提高了约 15%。分析了 12 种中间产物的毒性，并研究了 TIA 的降解机理。
