摘要:
采用电-Fenton法对麻醉药瑞芬太尼合成过程中的中间体1-苄基-4-氨甲酰基-4-苯胺基哌啶（简称酰胺, AMIDE）模拟废水进行了降解研究, 结果表明, 在以石墨为阴极、铁为阳极的模式下, 当pH为3、电解电压为3 V、投加H2O2浓度为10 mmol/L时, 室温下电解浓度为20 mg/L的酰胺废水60 min后, 酰胺的去除率高于99%, TOC去除60%。通过紫外光谱(UV)、红外光谱(IR)及HPLC检测酰胺的降解产物, 说明电-Fenton法能使废水中目标化合物的环结构破坏, 快速而完全地转
Abstract:
An electro-Fenton method was investigated for the treatment of pharmaceutical wastewater from intermediate i.e. 1-benzyl-4-carbamoyl-4-anilinopiperidine (ab. AMIDE) synthetic process using a graphite cathode and a Fe anode. The factors affecting the removal efficiency of AMIDE has been optimized. The results showed that the optimal conditions were as follows: room temperature, initial pH 3,AMIDE concentration of 20 mg/L, electrolytic voltage of 3 V, dosage of H2O2 of 10 mmol/L and reaction duration of 60 min. Under these conditions, the removal of AMIDE achieved higher than 99%, while the decay of TOC was obtained as 60%. Results of HPLC, UV and IR further confirmed that the rings of AMIDE were broken and AMIDE could be rapidly and completely converted into small organic molecules but could not be mineralized into CO2 totally using electroFenton process. The investigation of this paper should be of benefit in the subsequent treatment of actual wastewater.
