摘要: Abstract Catalytic particle electrodes (CPEs) were developed from steel slag waste, and used to degrade Rhodamine B (RhB). To improve degradation efficiency, Mn-loaded CPEs with good reproductive performance constructed through ultrasound impregnation–calcination strategy. The resulting samples characterized by XRF, SEM, EDS, XPS XRD. Degradation efficiency of the systems 93.22% without air supply in 80 min. And for reached 100% 50 min. Furthermore, enhanced mechanism was proposed. high could be ascribed increase hydroxyl radicals originated electro-Fenton.
