Fe-doped graphite phase carbon nitride(g-C3N4)was irradiated to prepare iron-doped dis-persed carbon nitride.The materials were characterized by SEM,XRD and FTIR.Electron beam irradia-tion changed the band structure of graphite phase carbon nitride,and Fe doping inhibited the recombi-nation of photogenerated electron hole pairs.An experimental study on the reduction capacity of Cr(Ⅵ)in wastewater by Fe-doped dispersed carbon nitride under photocatalytic conditions was carried out.Relevant experiments were carried out on the influence factors such as electron beam irradiation dose,catalyst type,catalyst dosage and Fe doping amount.The experimental results showed that:When the electron beam irradiation dose is 30 kGy and the doping ratio of Fe is 10％,the degradation effi-ciency of Cr(Ⅵ)is the highest,and the degradation rate within 180 min is 95％,which is more than 4 times that of pure graphite phase carbon nitride.
