Özet:

 In the present study, peroxymonosulfate and hydrogen peroxide activation performances of various layered double hydroxide LDH catalysts were tested for the removal of the model food dye, tartrazine, from aqueous solutions. Catalytic activities of Cu-Fe-LDH, Co-Fe-LDH and Ni-Fe-LDH were compared in the presence of peroxymonosulfate and hydrogen peroxide. In the catalyst screening experiments performed by using different oxidants, Co-Fe-LDH and peroxymonosulfate were determined as the most suitable catalyst and the oxidant, respectively. The interactive effects of the catalyst loading, pH and the molar ratio of the oxidant to dye were investigated and the reaction conditions were optimized by using Box-Behnken Design and response surface methodology. Under the optimum reaction conditions determined as 2 gL of catalyst loading, pH 3, and 11.36 oxidantdye molar ratio, 87.35 organic matter removal and 97.47 decolorization efficiencies were achieved.

 Bu çalışmada, çeşitli tabakalı çift hidroksit TÇH katalizörlerinin peroksimonosülfat ve hidrojen peroksit aktivasyonu performansları, model gıda boyası olarak seçilen tartrazinin sulu çözeltilerden uzaklaştırılmasında test edilmiştir. Cu-Fe-TÇH, Co-Fe-TÇH ve Ni-Fe-TÇHnin peroksimonosülfat ve hidrojen peroksit varlığında katalitik aktiviteleri karşılaştırılmıştır. Farklı oksidanlar kullanılarak gerçekleştirilen katalizör tarama deneylerinde Co-Fe-TÇH ve peroksimonosülfat en uygun katalizör ve oksidan olarak belirlenmiştir. Katalizör yüklemesi, pH ve oksidanboya molar oranının etkileşimli etkileri araştırılmış ve Box-Behnken Design ve tepki yüzeyi metodolojisi kullanılarak reaksiyon koşulları optimize edilmiştir. 2 gL katalizör yüklemesi, pH 3 ve 11,36 oksidanboya molar oranı olarak belirlenen optimum reaksiyon koşullarında 87.35 organik madde giderimi ve 97.47 renk giderimi elde edilmiştir.
