•Satisfactory degradation efficiency of pollutants was achieved by FeS/PAA system.•S(-II) and H2S (aq) played a significant role in Fe(II) regeneration.••OH played a dominant role in pharmaceuticals degradation.•The R-O• generated was supposed to be quickly consumed by sulfur specie.•Degradation pro...
