  • 摘要: 苯胺黑药(学名:二苯胺基二硫代磷酸)是一种良好的有色金属硫化矿浮选捕收剂,属于典型的难降解有机污染物。为研究臭氧氧化苯胺黑药的条件和氧化反应的动力学,选用臭氧作为氧化剂,对苯胺黑药浓度和模拟废水的COD进行测定。结果表明,用5 g/h的臭氧氧化20 min后,初始浓度50、75和150 mg/L的苯胺黑药模拟废水的COD去除率分别为56%、59%和76%,苯胺黑药浓度的去除率分别达到100%、99%和88%,反应后废水pH变为强酸性(k为-0.372 s-1、-0.331 s-1和-0.259 s-1;R2为0.9926、0.9949和0.9903。探讨了臭氧氧化苯胺黑药前后pH变化的机理。
    Abstract: Aniline aerofloat (scientific name: dianilino dithiophosphoric acid), which is a good non-ferrous metal sulfide ore flotation collecting agent, belongs to the typical refractory organic pollutants.This study analyzed the conditions of aniline aerofloat being oxidized by ozone associated with its dynamic of oxidation reaction. For this purpose, ozone was selected as the oxidant to determine the concentrations of aniline aerofloat and the COD of simulated wastewater. The results show that after using 20 minutes ozone oxidation in 5 g/h, the COD removal rates are 56%, 59% and 76% for simulated wastewater with 50, 75 and 150 mg/L of initial aniline aerofloat concentrations respectively, while the aniline aerofloat removal rate reached 100%, 99% and 88% in the order mentioned. Meantime, the pH of the wastewater after oxidation becomes less than 4, which indicates a strong acid. The oxidation kinetics of the apparent first-order rate constant k are -0.372 s-1, -0.331 s-1 and -0.259 s-1; R2 are 0.9926, 0.9949 and 0.9903. A discussion about the mechanism of pH change before and after aniline aerofloat being oxidized by ozone is presented.
