Umphumo we-Cl (-) kwi-oxidative degradation ye-Acid Orange 7 (AO7) iphandwa kwi-UV / S2O8 (2-) inkqubo ukucacisa iindlela ze-chlorination kumanzi amdaka e-saline.Isixa esisezantsi se-Cl(-) kunye ne-Br(-) iphucule ukonakala kwe-AO7, kodwa isiphumo esinjalo sonyuselo sehliswe kancinci kancinci ngokunyuka kwedosi ye-halide ion.I-mineralization yedayi ifunyenwe inqandelwe yi-Cl (-), ngakumbi phantsi kweemeko ze-acidic.Iziphumo ze-kinetics modeling zibonise ukuba iqhezu leeradicals ezahlukeneyo ze-oxidizing lixhomekeke kakhulu kumxholo we-Cl(-).Kwi-pH yokuqala ye-6.5, i-Cl2(-) yayininzi kakhulu kune-SO4 (-).Ukubaluleka kwe-Cl2(-) ye-AO7 yokuthotywa kunyuke ngokunyuka kwe-Cl(-) yoxinaniso kwaye yongamele leyo ye-SO4(-) ku- [Cl(-)]>1mM.Ngaphandle kwe-Cl (-), i-SO4 (-) yayiyeyona nto iphambili yokuthotywa kwe-AO7 phantsi kweemeko ze-acidic, ngelixa i-OH iphumelele ngokuthe ngcembe kwi-pH ephezulu.Ngaphantsi kweemeko eziphezulu zetyuwa, i-OH eninzi inokuqulunqwa kwaye ibe negalelo kwi-dayi degradatio n ngokukodwa kwi-alkaline medium, ekhokelela ekusebenzeni okuphezulu kokutshabalalisa kwe-AO7.Iimveliso ezininzi zeklorini zifunyenwe phambi kwee-ion ze-chloride, kunye ne-SO4 (-) / Cl2 (-)-based degradation pathways ye-AO7 yacetywayo.Lo msebenzi ubonelela ngokuqonda ngakumbi iindlela zokusabela ezintsonkothileyo ze-SO4 (-)-esekelwe kwiinkqubo ze-oxidation eziphambili kwiindawo ezityebileyo ze-chloride.
