Traditional Fenton system has the disadvantages of low H2O2 utilization efficiency, high remediation cost and great environmental side effect. A new type of advanced oxidation system Fe(Ⅱ)/O2/sodium tripolyphosphate (STPP) was proposed to ease these disadvantages. Oxygen gas was used,as the oxidant to replace H2O2.STPP, an inorganic ligand, has the ability to form complexation with Fe(Ⅱ), which could greatly activates O2 to form reactive oxygen species. This studyinvestigated the degradation rhodamine B decreased by > 70%at pH between 5~9. No remarkable effect was observed on the degradation of rhodamine B by common metal ions. The results of scavenger experiments show that×OH was the main reactive oxygen species for contaminant degradation. This new reaction system is more green sustainable, and has a wide application prospect in refractory wastewater treatment.
