Cu-Fe-TÇH, Co-Fe-TÇH ve Ni-Fe-TÇH’nin 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 oksidan/boya molar oranının etkileşimli etkileri araştırılmış ve Box-Behnken Design ve tepki yüzeyi metodolojisi kullanılarak reaksiyon koşulları optimize edilmiştir. 2 g/L katalizör yüklemesi, pH 3 ve 11,36 oksidan/boya molar oranı olarak belirlenen optimum reaksiyon koşullarında %87.35 organik madde giderimi ve %97.47 renk giderimi elde edilmiştir. KW - Tabakalı Çift Hidroksit KW - Gıda Boyası KW - Box-Behnken Tasarımı KW - İleri Oksidasyon Prosesleri KW - Peroksimonosülfat Aktivasyonu KW - Hidrojen Peroksit Aktivasyonu N2 - 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 g/L of catalyst loading, pH 3, and 11.36 oxidant/dye molar ratio, 87.35% organic matter removal and 97.47% decolorization efficiencies were achieved.
