Sentetik Atıksulardan Elektrooksidasyon Yöntemiyle Renk Gideriminin Araştırılmasında Başlangıç Boyar Madde Kirliliği ve Sıcaklığın Etkisi

Abstract

Bu çalışmada sentetik atıksulardan elektrooksidasyon yöntemiyle renk giderimi araştırılmıştır. Denemeler kesikli modda gerçekleştirilmiştir. Sistem 5 anot ve 5 katottan oluşturulmuş ve akım doğru akım güç kaynağı ile kontrol edilmiştir. Katot malzemesi olarak paslanmaz çelik katotlar, anot malzemesi olarak karışık metal oksit kaplama (Ti/IrO2/RuO2) anotlar tercih edilmiştir. Metilen mavisi boyar maddesinin kullanıldığı çalışmalarda, renk giderimi üzerine başlangıç boyar madde konsantrasyonu ve atıksu sıcaklığının etkisi incelenmiştir. Sonuçlar artan boyar madde kirliliği ile giderilen boyar madde miktarının azaldığını göstermiştir. Ayrıca artan atıksu sıcaklığının giderim verimini artırmıştır. Başlangıç boyar madde konsantrasyonunun etkisinin incelendiği çalışmalarda giderim verimleri 30 dakikalık deneme süresi sonunda 25 mg/L, 50 mg/L, 100 mg/L ve 250 mg/L için sırasıyla %99,99, %99,31, %96,38 ve %77,89 olarak elde edilmiştir. Sıcaklık etkisinin incelendiği çalışmalar 10°C, 20°C, 30°C ve 40°C için incelenmiş ve elde edilen giderim verimleri sırasıyla %98,22, %99,31, %99,67 ve %99,99 olarak ölçülmüştür. Sonuçlar sentetik atıksulardan renk giderimi için elektrooksidasyon prosesinin uygulanabileceğini göstermektedir

The Effect of Initial Dyestuff Pollution and Temperature on the Investigation of Color Removal from Synthetic Wastewater by Electrooxidation Method

Abstract

In this study, color removal from synthetic wastewater by electrooxidation method was investigated. The experiments were carried out in batch mode. The system is composed of 5 anodes and 5 cathodes, and the current is controlled by a direct current power supply. Stainless steel cathodes were preferred as the cathode material, and mixed metal oxide coated (Ti/IrO2/RuO2) anodes were preferred as the anode material. The effects of initial dyestuff concentration and wastewater temperature on color removal were investigated using Methylene Blue (MM) dyestuff. The results showed that the amount of dye removed decreased with increasing dye pollution. In addition, the increased wastewater temperature increased the removal efficiency. In studies examining the effect of initial dye concentration, removal efficiencies were 99.99%, 99.31%, 96.38%, and 96.38% for 25 mg/L, 50 mg/L, 100 mg/L, and 250 mg/L, respectively, at the end of the 30-minute trial period. It was obtained as 77.89%. Studies examining the effect of temperature were examined for 10°C, 20°C, 30°C and 40°C and the obtained removal efficiencies were measured as 98.22%, 99.31%, 99.67% and 99.99%, respectively. The results show that the electrooxidation process can be applied for color removal from synthetic wastewaters.
