Usage of advanced oxidation processes (AOPs) as a pretreatment or post treatment have
showed tremendous potential in order to overcome negative effects on the conventional
treatment processes which used for the treatment of industrial wastewater that include
various toxic and refractory organic substances, In this study, removal of phenol, 2,4-
dichlorophenol solution by using advanced oxidation process (UV/H2O2, Fenton’s Reagent,
and Photo-Fenton) was investigated. Based on the phenol and total organic carbon analyzes,
it was found that reaction time and oxidant dosage requirement which is needed to almost
mineralization and degradation of phenol and 2,4-dichlorophenol solution by photo fenton
process is lower than other processes

Toksik ve kalıcı özellikte organik maddeler içeren endüstriyel atıksuların arıtımında
kullanılan klasik arıtma yöntemlerinin olumsuz etkilerini engelleyebilmek için ön arıtma veya
son arıtma kademesi olarak ileri oksidasyon proseslerinin (İOP) kullanımı son zamanlarda
oldukça önem kazanmaktadır. Bu çalışmada, fenol, 2,4-diklorofenol organik maddelerini
içeren sentetik atıksuların ileri oksidasyon prosesleri (UV/H2O2, Fenton ve Foto-Fenton) ile
arıtılabilirliği araştırılmıştır. Toplam organik karbon ve fenol analizleri sonucunda, FotoFenton
prosesi ile fenol ve 2,4-diklorofenol içeren atıksuların tamamen mineralize olması ve
parçalanabilmesi için gerekli olan reaksiyon süresi ve oksidan madde gereksiniminin diğer
ileri oksidasyon proseslere göre daha az olduğu saptanmıştır
