UV/Güneş Işığı Kaynağı Altındaki Atık Sudaki Siyanür İçeriğini Gidermek İçin Sol-jel Metodu ile V, Er ve Ce Katkılandırılmış TiO2 Filmlerin Sentezlenmesi

Bu çalışmada, atık sudaki siyanürün fotokatalitik bozunmasını sağlamak için kaplanmış altlıklar üzerine endüstriyel ölçekte sol-jel tekniğiyle Vanadyum (V), Erbiyum (Er) ve Seryum (Ce) kakılandırılmış TiO2filmlerin cam altlıklar üzerine kaplanmıştır. İnce filmlerin yapısal, mikroyapısal ve elektriksel özellikleri incelenmiş ve cam üzerine kaplanmış filmler UV/güneş ışık kaynağı altında atık sularda siyanürün fotokatalitik bozunmasında fotokatalizör olarak kullanılmıştır. Modifiye edilmiş TiO2 filmler kullanılarak atık sulardaki bozunmada % 85-90 verim elde edildiği bulunmuştur.

Synthesis of V, Er and Ce Substitued TiO2 Films via Sol-gel Method to Degrade Cynanide Content in Waste Water Under UV/Sunlight Source

In this study, Vanadium (V), Erbium (Er) and Cerium (Ce) substituted TiO2 films were deposited on glass substrates via sol-gel technique in industrial scale in order to provide photocatalytic degradation of cyanide in waste water. Structural, microstructural and electrical properties of the thin films were examined and thin films coated on glass substrates were used as the photocatalyzer in the photocatalytic degradation of cyanide in waste waters under UV/sunlight source. It was found that 8590 % efficiency was obtained in degradation of cyanide in waste water using modified TiO2 films
