APPLICATION OF POLYCARBOXYLIC ACIDS AS BINDERS FOR TiO2 IMMOBILIZATION ON COTTON TEXTILES

Abstract: Immobilizing the photocatalyst on a support is an alternative solution to a critical issue in photocatalysis, which is the need for unit operations to remove the photocatalyst from the effluent. In this work, TiO 2 was immobilized onto a cotton textile substrate by polycarboxylic acid binders (succinic and citric acids) using a solution deposition method, and the most appropriate conditions for pre-treatment and the relationship between variables were determined by an experimental design. Then, samples prepare… Show more

“…On the other hand, the variation in nanomaterial content is determined by the extent of fixation and immobilization of used inorganic nanomaterials via chelation and electrostatic interactions, e.g. −COO − … Ag + and/or −COO − … TiO 4+ [1,39,41].…”

“…Asam sitrat merupakan asam polikarboksilat, 24 dan dapat bereaksi dengan kain kapas melalui reaksi esterifikasi. Gugus karboksilat dari asam sitrat akan bereaksi dengan gugus -OH dari selulosa kain kapas, seperti ditunjukkan pada Gambar 4 25 dan Gambar 5. 26 Untuk mengevalusi keberhasilan proses imobilisasi maka dilakukan pengukuran % add on, yaitu persentase penambahan massa pada kain yang diimobilisasi setelah dikurangi massa kain sebelum diimobilisasi.…”

“…The authors commented that TiO 2 immobilization forms stable and active materials at prolonged UV irradiation periods. 23 Asgharian-Dastenaie et al 24 investigated the effect of TiO 2 nanoparticles and polycarboxylic agent onto cotton fabric samples. They pointed out that self-cleaning property against chemical and natural stains was improved.…”
