Abstract: Carbamazepine is degraded by ferrous ion activated hydrogen peroxide and persulfate (Fe2+-activated H2O2/PS) and the influencing factors are studied.It is shown that the degradation rate of carbamazepine can reach 62.9% in 30 minutes when n(H2O2)/n(PS) is 3:1,Fe2+ dosage is 0.1 mmol·L-1 and the appropriate pH values is 3.Increasing Fe2+ dosage can improve the degradation efficiency of carbamazepine.Increasing the initial concentration of carbamazepine will reduce the removal rate of carbamazepine but can enhance its total removal amount.Besides,hydroxyl radicals are proven to be the predominant active species in the Fe2+-activated H2O2/PS system by using methanol and tertiary butanol as scavengers.This research provides a type of technology reference for the treatment of carbamazepine.
