Abstract

Poli(etilen glikol dimetakrilat-2-vinil piridin)-TiO2 [poli(EGDMA-2-VP)] - TiO2 mikro küreleri, tekstil boyar maddelerinin sulu çözeltiden fotokatalitik renk giderimi için süspansiyon polimerizasyon yöntemi ile sentezlendi. Sentezlenen çapraz bağlı [poli (EGDMA-2-VP)] - TiO2 mikro küreleri, taramalı elektron mikroskobu (SEM), X-ışını difraktometresi (XRD) ve fourier dönüşümlü kızılötesi spektroskopisi (FTIR) ile karakterize edildi. Elde edilen mikro kürelerin boyar madde renk gidermede kullanılabilirliğini araştırmak için pH, polimer miktarı, zaman ve boya konsantrasyonu parametreleri, hem güneş ışığı altında hem de 366 nm UV ışığı altında incelendi. Boyar maddenin maksimum fotokatalitik renk gideriminin meydana geldiği optimum koşullar pH 3, polimer miktarı 0.05 g, boya konsantrasyonu 30 mg/L ve süre 5 saattir.

Investigation of Photocatalytic Decolorization Parameters of Acid Violet 7 Dye With poly(ethylene glycol dimethacrylate-2-vinyl pyridine) -TiO2 Photocatalytic Polymer Microbeads

Abstract

Poly(ethylene glycol dimethacrylate-2-vinyl pyridine)-TiO2 [poly (EGDMA-2-VP)] - TiO2 microbeads were synthesized by suspension polymerization method for photocatalytic decolorization of textile dyes from aqueous solution. The synthesized cross-linked [poly (EGDMA-2-VP)] - TiO2 microbeads were characterized by scanning electron microscopy (SEM), X-ray Diffraction (XRD)
and fourier transform infrared spectroscopy (FTIR). To investigate the usability of the obtained microbeads in dye decolorization, the paramreters such as pH, polymer amount, time, and dye concentration were examined both under sunlight and 366 nm UV light. Optimum conditions under which maximum photocatalytic decolorization of the dye were pH 3, polymer amount 0.05 g, dye concentration 30 mg /L and time 5 hours.
