文摘

FeS2/SiO2 microspheres made the reaction of Fe2+ and H2O2 smoothly continuous. Stability of FeS2/SiO2 microspheres was superior to that of bare FeS2. A low EDTA concentration did positively affect the degradation rate of CIP. An enhanced CIP degradation was due to both adsorption and oxidation processes. A reaction pathway mechanism for the enhanced degradation of CIP was proposed.
