Abstract

In this study, microelectrolysis (ME) method was used for the treatment of the Reactive Black 5, which is a type of azo dye from the model wastewater. ME reactor was filled by iron chip-granular activated carbon (Fe/C) or carbon steel-granular activated carbon (CS/C) mixtures. In microelectrolysis experiments the effects of operational parameters such as initial RB5 concentration (50-150 mg/L), the pumping speed of the solution (30-60 rpm), initial pH value of the solution , solution conductivity (3-9 mS/cm) and temperature (25-45 oC) were examined. Under the conditions of an initial pH of 3, RB5 concentration of 50 mg/L, pumping speed of 30 rpm, and conductivity of 3 mS/cm, the dye removal efficiencies of 97.5% for Fe/C filling and 96.6% for CS/C filling were achieved

MİKROELEKTROLİZ YÖNTEMİ İLE MODEL ÇÖZELTİDEN REAKTİF BLACK 5 GİDERİMİ

Abstract

Bu çalışmada bir azo boya olan Reaktif Black 5 (RB5) içeren model atık suyun arıtımı için mikroelektroliz (ME) yöntemi kullanıldı. Demir talaşı-granül aktif karbon (Fe/C) ve karbon çeliği-granül aktif karbon (KÇ/C) karışımları ME reaktörü dolgusu olarak kullanıldı. Mikroelektroliz deneylerinde boya derişiminin (50-150 mg/L), çözelti pompalama hızının (30-60 rpm), çözelti pH değerinin (2-4), çözelti iletkenliğinin (3-9 mS/cm) ve sıcaklığın (25-45 ⁰C) boya giderim yüzdesine olan etkileri incelendi.  Her iki dolgu için de çalışılan parametrelerin en uygun değerleri pH=3, 50 mg/L boya derişimi, 30 dev/dk pompalama hızı ve 3 mS/cm iletkenlik olarak belirlendi. Bu koşullarda (Fe/C) dolgu ile %97,5; (KÇ/C) dolgu ile %96,6’ lık RB% giderimine ulaşıldı.
