Ua noiʻi ʻia ka hopena o Cl(-) i ka hoʻohaʻahaʻa oxidative o Acid Orange 7 (AO7) i loko o ka ʻōnaehana UV/S2O8(2-) e hoʻomaʻamaʻa i nā ala chlorination i nā wai ʻōpala paʻakai.ʻO ka nui haʻahaʻa o Cl(-) a me Br(-) i hoʻonui i ka decoloration o AO7, akā ua emi mālie kēlā hopena hoʻolaha me ka piʻi ʻana o ka nui o ka halide ion.Ua ʻike ʻia ka hoʻokaʻawale ʻana o ka mineralization e Cl (-), ʻoi aku ka nui ma lalo o nā kūlana acidic.Ua hōʻike ʻia nā hopena o ka hoʻohālike kinetics ʻo ka hapa o nā radical oxidizing like ʻole i hilinaʻi nui ʻia i ka ʻike o Cl(-).Ma ka pH mua o 6.5, ua oi aku ka nui o Cl2(-) mamua o SO4(-).Ua hoʻonui ʻia ke koʻikoʻi o Cl2 (-) no ka hoʻohaʻahaʻa ʻana o AO7 me ka piʻi ʻana o ka Cl (-) ka hoʻonui ʻana a hoʻonui i ko SO4 (-) ma [Cl (-)]>1mM.Me ka ʻole o Cl(-), ʻo SO4(-) ka radical nui no ka hoʻohaʻahaʻa ʻana o AO7 ma lalo o nā kūlana acidic, ʻoiai ua lanakila mālie ʻo OH ma ka pH kiʻekiʻe.Ma lalo o nā kūlana paʻakai kiʻekiʻe, hiki ke hoʻokumu ʻia ka OH hou aʻe a hāʻawi ʻia i ka degradation dye n ʻoi loa i loko o ke ʻano alkaline, e alakaʻi ana i ka ʻoi aku ka maikaʻi o ka luku ʻana o AO7.Ua ʻike ʻia kekahi mau huahana chlorinated ma ke alo o nā ion chloride, a ua manaʻo ʻia nā ala hoʻohaʻahaʻa ma muli o SO4(-)/Cl2(-) o AO7.Hāʻawi kēia hana i ka ʻike hou aʻe o nā mīkini hoʻololi paʻakikī no nā kaʻina hana hoʻonaʻauao kiʻekiʻe e pili ana i ka SO4(-) i nā kaiapuni waiwai chloride.
