  • 摘要: 以新烟碱类杀虫剂呋虫胺为目标污染物,以过硫酸钾为氧化剂,研究不同热活化条件下过硫酸钾对呋虫胺降解率的影响。实验结果表明:呋虫胺的降解率与溶液中过硫酸钾的浓度成正比;随着温度的升高,呋虫胺的降解率也逐渐升高;虽然中性时呋虫胺的降解率稍高于酸性和碱性时的降解率,但pH的变化对呋虫胺的降解率影响不大;Cl-和HCO3-对反应的影响比较复杂,当溶液中的Cl-和HCO3-的浓度低于5 mmol/L时,均促进呋虫胺的降解,而浓度升高时则抑制呋虫胺的降解;通过添加自由基捕获剂发现,该反应体系中同时存在·SO4-和·OH,但起主要作用的是·SO4-。
    Abstract: Dinotefuran and potassium persulfate solution were chosen as the target pollutant and oxidant to investigate the degradation reaction of dinotefuran in different heat-activated persulfate oxidation processes. The results showed that the degradation rate of dinotefuran increased with increasing persulfate concentration, while temperature also promoted the degradation of dinotefuran. The degradation rate of dinotefuran was slightly higher under neutral and acidic conditions than that under alkaline conditions, but the change in pH made little difference to the degradation. Cl- and HCO3- had a complex effect on the degradation of dinotefuran in water. When the concentration of Cl- and HCO3- was less than 5 mmol/L, the degradation of dinotefuran was promoted, whereas high concentrations of Cl- and HCO3- inhibited the degradation of dinotefuran. The radical scavenger test indicated that ·SO4- and ·OH existed in this reaction, and ·SO4- played a major role in the process.
