چکیده
Five organic fertilizers (DTPA, EDDHA, HEDTA, EDTA and EDDS) were studied as iron sources for photo-Fenton process at natural pH to remove micropollutants (MPs) from wastewater its reuse in irrigation. The results demonstrated that the stability constant of chelates is a key parameter optimal removal it linked structure chelator. Mixtures also tested overcome excessive loose optimize MPs abatement kinetics. An improvement occurred when using chelating mixtures. For instance, with 50 %EDDS + %EDTA total propranolol (PROP) was achieved 30 min while needed up 90 reaction EDDS degradation not achieved. In addition, availability dissolved mixture end treatment 5.5 times higher than EDDS, increasing suitability water
