Bu çalışma, Alcain Mavisi 8GX boya çözeltilerinin demir (II) iyonu ve ısı aktivasyonuna dayalı persülfat oksidasyonu ile sulardan arıtımını içermektedir. Giderim çalışmaları üç farklı sıcaklık (40 oC, 60 oC ve 80 oC) ve farklı boya:Fe2+:persülfat molar dozlarında (1:1:1, 1:2:1, 1:1:0.5, 1:4:1) gerçekleştirilmiştir. Buna ilaveten, pH’ın giderime etkisi iki farklı pH koşullarında (3 ve 5.7) test edilmiştir. Sonuçlar, artan sıcaklığın ve persülfat dozunun Alcain Mavisi 8GX giderimini artırdığını göstermiş ve pH 3 koşullarında 90 dakika sonunda 80 oC sıcaklıkta % 91 giderilmiştir. Fe2+/Persülfat yöntemi ise 1:1:1 boya:Fe2+:persülfat molar dozunda pH 3 koşullarında 90 dakika sonunda % 73 boya giderimi sağlamıştır; 1:2:1 koşullarında pH 5.7’de ise % 72 giderim gözlenmiştir.

Acid Blue 113 Degradation and Mineralization by UV/Persulfate Process

Öz

In this work, decolorization of reactive Alcain Blue 8GX dye solution were investigated by persulfate oxidation activated by ferrous ion and heat. Three different temperature (40 °C, 60 °C and 80 °C) were tested during heat activated persulfate and ferrous ion activated persulfate were tested under various molar ratios of dye:Fe2+:persulfate ratio (1:1:1, 1:2:1, 1:1:0.5, 1:4:1). In addition, pH effect has been tested at ambient conditions (5.23) and pH of 3. The results showed that increasing the temperature and persulfate concentration was favorable to the degradation of the dye with decolorization efficiency as high as 91 % observed at 80 ℃ after 90 minutes of reaction at pH 3. The ratio 1:1:1 decolorized AB 8GX 73 % at pH of 3 and 72 % at pH 5.7 after 90 minutes.
