It is known that photocatalytic techniques have advantages over other
conventional treatment techniques. In this study, nanoparticle Ti (II) oxide (~
10 nm) and hydrogel polymer based heterogeneous catalysts were produced to
maximize photo-catalytic activity. The performance of the obtained
photo-catalytic material was evaluated in the process of removing reactive
textile dyes from aqueous media. When the Ti (II) oxide nanoparticles were used
directly for representative reactive textile dyes, alizarin red S, Congo red,
methylene orange and acid blue (20 ppm dye, 10 ppm catalyst, 60 minutes and 25
° C) which are extremely hazardous for human and environmental health even at
low concentrations, up to 92.5% decomposition was achieved, while 71.2%
decomposition was obtained with Ti (II) oxide nanoparticle embedded
microparticles. However, given the advantages of removing the catalyst, the
indicated performance reduction is not critical. By scaling the reaction
conditions, high removal performance can be achieved.

Ti(II) Oksit Nanoparçacık Yüklenmiş GMA-co-EGDMA Mikroküreler: Tekstil Boyalarının Sulu Ortamdan Fotokatalitik Giderimi

Öz

Atık suların arıtılmasında,
özellikle tekstil boyalarının sulu ortamdan uzaklaştırılmasında, fotokatalitik
teknikler birçok avantaja sahiptir. Bu çalışmada, fotokatalitik aktiviteyi en
yüksek seviyeye çıkarmak için, nanoparçacık Ti (II) oksit (~10 nm) ve hidrojel
polimer esaslı heterojen katalizörler üretilmiştir. Elde edilen foto-katalitik
malzemenin performansı, sulu ortamlardan reaktif tekstil boyalarının
giderilmesi işleminde değerlendirilmiştir. Düşük miktarlarda bile çevre ve
insan sağlığına etkisi olan reaktif tekstil boyaları arasından model olarak
seçilen alizarin kırmızısı S, Kongo kırmızısı, metilen turuncusu ve asit mavisi
için Ti(II) oksit nanoparçacıklar doğrudan kullanıldığında (20 ppm boya, 10 ppm
katalizör, 60 dakika ve 25°C’ta) %92.5’a varan bozunma elde edilirken,
mikrokürelere yüklenmiş nanoparçacıklar ile %71.2 bozunma elde edilmiştir.
Ancak, katalizörün ortamdan alınması dikkate alındığında, belirtilen performans
azalması önemli değildir. Reaksiyon ortamının ölçeklendirilmesi ile yüksek
giderim performansı elde edilebilir.
