Cov nyhuv ntawm Cl(-) ntawm oxidative degradation ntawm Acid Txiv kab ntxwv 7 (AO7) tau tshawb xyuas hauv UV / S2O8(2-) system kom elucidate chlorination txoj hauv kev hauv cov dej qab ntsev.Cov nqi qis dua ntawm Cl(-) nrog rau Br(-) txhim kho qhov decoloration ntawm AO7, tab sis cov txiaj ntsig zoo li no txo qis nrog qhov nce halide ion ntau npaum.Cov dye mineralization tau pom tias inhibited los ntawm Cl(-), tshwj xeeb tshaj yog nyob rau hauv acidic tej yam kev mob.Cov txiaj ntsig ntawm kinetics qauv qhia tau hais tias feem ntau ntawm cov oxidizing sib txawv radicals feem ntau nyob ntawm cov ntsiab lus ntawm Cl (-).Thaum pib pH ntawm 6.5, Cl2(-) muaj ntau dua li SO4(-).Qhov tseem ceeb ntawm Cl2(-) rau AO7 degradation tau nce nrog nce Cl(-) concentration thiab overwhelmed ntawm SO4(-) ntawm [Cl(-)]> 1mM.Yog tsis muaj Cl(-), SO4(-) yog qhov tseem ceeb tshaj plaws radical rau AO7 degradation nyob rau hauv acidic tej yam kev mob, thaum OH prevailed maj mam ntawm siab dua pH.Nyob rau hauv siab salinity tej yam kev mob, ntau OH tuaj yeem tsim thiab pab rau cov dye degradatio n tshwj xeeb tshaj yog nyob rau hauv nruab nrab alkaline, ua rau muaj kev puas tsuaj ntau dua ntawm AO7.Ob peb chlorinated byproducts tau kuaj pom muaj chloride ions, thiab SO4(-) / Cl2(-)-raws li degradation txoj kev ntawm AO7 tau npaj.Qhov kev ua haujlwm no muab kev nkag siab ntxiv txog cov txheej txheem tshuaj tiv thaiv nyuaj rau SO4 (-)-raws li cov txheej txheem oxidation siab hauv cov chloride-nplua nuj ib puag ncig.
