摘要：

Gamma radiation (GR) is a promising technique, among known advanced oxidation processes, degrading water contaminants. Nevertheless, few authors report the degradation of sulfonamides by GR, and limited information exists concerning the use of GR in the case of sulfadiazine (SDZ). The objectives of this work are (1) evaluating GR as an alternative method for treating wastewater contaminated with SDZ and examinating the intensification of GR with oxidants (H2O2 or Fenton reagent). GR was performed with a high-activity Co-60 source. The gamma radiation/Fenton process gave the best result, leading to total SDZ removal and high (74.13%) pollutant mineralization.
