In this study, the removable of Methylene Blue (MB) was investigated by Fenton-like
oxidation process. The removal yield was evaluated associated with color and chemical
oxygen demand (COD). Feo
, H2O2 and initial dyestuff concentrations and pH were considered
in determination of optimum conditions for the process. At the end of reaction for 20 minutes
the optimum values were found as Feo=0.1 gL-1
, H2O2 =75 mgL-1
and pH=3.0. The color of
99.0% and COD of 84.6% removal were obtained at the MB concentration of 100 mg L-1
for
these values. Increasing of dyestuff concentration reduced both color and COD removal

Anahtar Kelimeler

Fenton-like oxidation, Dye, COD removal

Öz

Bu çalışmada Methylene Blue (MB) boyar maddesinin Fenton-benzeri oksidasyon işlemi ile arıtılabilirliği araştırılmıştır. Arıtma verimi renk ve Kimyasal Oksijen İhtiyacı (KOI) parametreleri ile değerlendirilmiştir. Bu işlem için optimum şartların belirlenmesinde Feo ve H2O2 konsantrasyonu, pH ve başlangıç boyar madde konsantrasyonu dikkate alınmıştır. Buna göre 20 dakikalık bir reaksiyon sonunda optimum değerler ; Feo=0.1 gL-1, H2O2=75 mgL-1ve pH=3.0 olarak bulunmuştur. Bu değerler için 100 mgL-1 MB konsantrasyonunda % 99.0 renk ve % 84.6 KOI giderim verimi elde edilmiştir. Boyar madde konsantrasyonunun artması hem renk hem de KOI giderme verimi düşürmüştür

Anahtar Kelimeler
