摘要：

以颗粒活性炭为载体,分别负载Fe³⁺、Cu²⁺或Fe³⁺-Cu²⁺制备出催化剂,采用微波/催化剂/H₂O₂工艺对酸性红B进行降解研究,并考察了各种因素对酸性红B降解效果的影响。研究结果表明,活性炭负载Fe³⁺-Cu²⁺型催化剂对酸性红B的处理效果最好,适宜的Fe³⁺、Cu²⁺负载量均为1.0%;对于100 mL初始质量浓度为100 mg/L的酸性红B模拟染料废水,适宜的处理条件为初始pH=3、催化剂投加量0.1 g、H₂O₂.05 mL、微波功率300 W。在此条件下处理4 min后酸性红B去除率超过99%,说明微波/催化剂/H₂O₂工艺能够有效去除酸性红B。

Abstract:

The catalyst has been prepared with granular activated carbon which is used as carrier and loaded with Fe³⁺，Cu²⁺or Fe³⁺-Cu²⁺ respectively. The research on the degradation is carried out by using microwave/catalyst/H2O2 process. The effects of various influencing factors on the degradation effectiveness of acidic red B are investigated.The results show that the treatment effectiveness of the catalyst using activated carbon which has been loaded with Fe³⁺-Cu²⁺ is the best. The appropriate carrying capacity of Fe3+ and Cu2+ are all 1.0%. For 100 mL of acidic red B simulated wastewater whose initial mass concentration is 100 mg/L，the appropriate treatment conditions are initial pH=3，catalyst dosage 0.1 g，H₂O₂ 0.05 mL and microwave power 300 W. Under these conditions，the removing rate of acidic red B after being treated for 4 min is more than 99%. It shows that the acidic red B can be removed by microwave/catalyst/H₂O₂ process effectively.
