摘要

使用芬顿试剂在间歇反应器中进行了环己胺 (CHA) 的氧化反应。研究了以下参数的影响:停留时间、pH 值、亚铁离子浓度和过氧化氢浓度。停留时间从 30 分钟到 2 小时不等,发现其影响显著为正。培养基的最佳 pH 值为 3。亚铁离子和过氧化氢的浓度范围分别为 0.1 克/升至 0.265 克/升和 0.5 克/升至 1.3 克/升。当亚铁离子浓度为 0.16 克/升、pH 值为 3 时,过氧化氢的影响非常显著。通过计算化学需氧量(COD)来衡量化学需氧量的去除率。COD 去除效率最高为 62%,氨产量最低为 14%。亚硝酸盐和硝酸盐的产量可以忽略不计。总之,结果证明了芬顿工艺处理 CHA 的有效性。

Study the influence of experimental conditions on the removal of organic compound in the Fenton process
The oxidation of cyclohexylamine (CHA) was carried out in a batch reactor, using Fenton’s reagent. The effects of the following parameters were investigated: residence time, pH level, ferrous ion concentration, and hydrogen peroxide concentration. Residence time ranged from 30 min to 2 h, and its effect was found to be significantly positive. A pH of 3 for the medium was observed to be optimum. Ferrous ion and hydrogen peroxide concentrations ranged from 0.1 g/l to 0.265 g/l and from 0.5 g/l to 1.3 g/l, respectively. The influence of hydrogen peroxide was significant at 0.16 g/l of ferrous ions and a pH of 3. CHA removal efficiency was measured by calculating chemical oxygen demand (COD). The maximum COD removal efficiency was 62%, and the minimum yield of ammonia was 14%. The yields of nitrite and nitrate were negligible. Overall, the results proved the effectiveness of the Fenton process for the treatment of CHA.
