摘　　要：采用简单的化学共沉淀法制得负载铁锰氧化物的磁性粉末活性炭(MACCs),对其物理特性进行了表征,并利用序批式反应装置研究了MACCs对水中磺胺甲恶唑(SMZ)的吸附去除效果。结果表明,MACCs具有与粉末活性炭相似的吸附性能,且具有良好的磁性,易于分离回收;MACCs的投加量和停留时间对处理效果影响较大,而搅拌速度的影响较小,当MACCs投加量>400 mg/L、停留时间为10 min时,对SMZ的去除率可达到100%。MACCs对SMZ的吸附容量较大,400 mg的MACCs可有效处理28 L、SMZ浓度为1 mg/L的水样。The magnetic powdered activated carbon composites （MACCs） loaded iron and manga- nese oxides prepared by using chemical co-precipitation, and its physical properties were characterized. The adsorption performance of sulfamethoxazole from water by MACCs was investigated in a sequencing batch reactor. The results showed that MACCs had similar adsorption performance to powder activated carbon and good magnetic properties, and it was easy to be separated and recycled. Compared to the stir- ring rate, the dosage and retention time of MACCs played a greater role in sulfamethoxazole removal. With MACCs dosage of more than 400 mg/L and retention time of 10 min, the removal rate of sulfame-thoxazole was 100%. MACCs had large adsorption capacity for sulfamethoxazole, and 400 mg MACCs could treat 28 L water that contained 1 mg/L sulfamethoxazole.
