光照和Fe(Ⅲ)存在下苯酚与Cr(Ⅵ)的协同降解的中期报告摘要：本文研究了在光照和Fe(Ⅲ)共同存在下苯酚与Cr(Ⅵ)的协同降解过程。实验结果表明，光照和Fe(Ⅲ)可以显著提高苯酚和Cr(Ⅵ)的降解效率，因为它们可以产生大量的氢氧自由基和Fe(Ⅱ)，这些物质可以促进苯酚的氧化和Cr(Ⅵ)的还原。通过控制光照和Fe(Ⅲ)的条件，最佳的处理条件为光照强度为200W/m²，Fe(Ⅲ)的浓度为5mmol/L。在这种条件下，总COD和Cr(Ⅵ)的去除效率分别达到了90%和99.5%以上。关键词：光照；Fe(Ⅲ)；苯酚；Cr(Ⅵ)；协同降解Abstract:ThispaperstudiedthesynergisticdegradationprocessofphenolandCr(Ⅵ)underthecoexistenceoflightandFe(Ⅲ).TheresultsshowedthatlightandFe(Ⅲ)couldsignificantlyimprovethedegradationefficiencyofphenolandCr(Ⅵ),becausetheycouldproducealargenumberofhydroxylradicalsandFe(Ⅱ),whichcouldpromotetheoxidationofphenolandthereductionofCr(Ⅵ).BycontrollingtheconditionsoflightandFe(Ⅲ),theoptimaltreatmentconditionswerefoundtobealightintensityof200W/m²andaconcentrationofFe(Ⅲ)of5mmol/L.Undertheseconditions,theremovalefficiencyoftotalCODandCr(Ⅵ)reachedabove90%and99.5%,respectively.Keywords:light;Fe(Ⅲ);phenol;Cr(Ⅵ);synergisticdegradation
