Study on treatment of pharmaceutical wastewater from intermediate synthetic process by electro-Fenton oxidation
电-Fenton法处理制药中间体废水的研究

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 H_2O_2 of 10 mmol/L and reaction duration of 60 min.Under...
