摘要

Homogeneous Fenton method has the characteristics of fast reaction and good degradation effect, but its economic cost is relatively high. If Fe^(2+) is not treated, it will also cause pollution. In order to make up for this defect, heterogeneous catalyst is considered to be prepared to use heterogeneous system to degrade benzoic acid wastewater. In this paper, the purchased AC particles were first crushed, graded and pretreated. Taking the pretreated sample as the carrier, the Fe / AC catalyst was prepared by immersing the carrier in 1g / L Fe^(2+) solution. The influence factors of catalyst preparation were analyzed by orthogonal test. It was found that the influence of particle size, calcination temperature and calcination time on catalyst activity increased in turn. Combined with TG-DSC, BET, XRD, SEM and other testing methods to characterize the supported catalyst, the optimal preparation conditions were determined to be a particle size of 60-100 mesh and calcined at 300℃for 4 h.
