Elektrokoagülayon Yöntemiyle Reaktif Yellow 160 Boyar Maddesinin Giderimi

Demir ve alüminyum elektrotlar ile donatılmış elektrokoagülasyon prosesinin (EP) kullanıldığı çalışmada Reaktif Yellow 160 (RY160) boyarmaddesi giderimi üzerine başlangıç pH, akım yoğunluğu, iletkenlik ve elektroliz süresinin etkisi incelenmiştir. EP’de elektrot materyalinden bağımsız olarak yüksek renk giderim verimi elde edilmiştir. Optimum işletme şartları alüminyum elektrot kullanılması durumunda, pH = 5, akım yoğunluğu 100 A/m2, elektroliz süresi 10 dakika, iletkenlik 1000 µS/cm iken demir elektrot kullanılması durumunda pH = 7, akım yoğunluğu 200 A/m2, elektroliz süresi 5 dakika, iletkenlik 1000 µS/cm olarak belirlenmiştir. Renk giderim verimi alüminyum elektrot çifti için 2,3 kWsa/m3 enerji sarfiyatı ve 0,52 $/m3 toplam maliyetle %96,4 iken demir elektrot çifti için 1,7 kWsa/m3 enerji sarfiyatı ve 0,28 $/m3 toplam maliyetle %95,8 elde edilmiştir. Sonuçlar, demir elektrot kullanımının alüminyum elektrot ile karşılaştırıldığında RY160 boyarmaddesinin gideriminde daha ekonomik olduğunu göstermiştir.

Decolorization of Reactive Yellow 160 Dye by Using Electrocoagulation

The effect of initial pH, current density, conductivity and electrolysis time on Reactive Yellow 160 (RY160) dye removal was investigated by using electrocoagulation process (EC) equipped with iron and aluminum electrodes couple. High color removal efficiency was obtained independent of electrode materials in EC. Optimum operational conditions was determined as pH = 5, current density 100 A /m2, electrolysis time 10 min and conductivity 1000 μS / cm for aluminum electrodes while it was pH = 7, current density 200 A/m2, electrolysis time 5 min and conductivity 1000 μS/cm for iron electrodes. Color removal was 96.4% with 2.3 kWh/m3 energy consumption and 0.52 $/m3 operating cost for aluminum electrode while it was 95.8% with 1.7 kWh/m3 energy consumption and 0,28 $/m3 operating cost for iron electrode. The results show that, iron electrodes are more cost effective than aluminum electrodes in removal of RY160 dye.
