عنوان انگلیسی Removal of Acid Blue 113 Textile Dye from Synthetic Aqueous Solution by Adsorption and Flocculation Process Using Cationic Copolymer Poly(n-hexadecyl-4-vinylpyridinium Bromide)
چکیده انگلیسی مقاله In this work, the retention of the acid blue113 (AB113) textile dye from synthetic dye solution by using cationic poly(n-hexadecyl-4-vinylpyridinium bromide) [P4VP-C16Br] was reported.
The removal of anionic dye was ascribed to two different processes. The first concerns the batch adsorption experiments performed to investigate the experimental parameters effect on the AB113 adsorption equilibrium. Then, the adsorption characteristics of copolymer via acid blue 113 in dilute aqueous solution were studied by UV-Vis spectrophotometroy. Indeed, the adsorption equilibrium was reached within 3 h of poly(4-vinylpyridine) quaternized at 50% and the adsorption kinetics is best described by a pseudo-second-order model. Additionally, the equilibrium modeling of AB113 removal process was described by Langmuir isotherms.
On the other hand, the second method was based on the flocculation process where use [P4VP-C16Br] as flocculant in its soluble form in acidic medium. Different parameters effecting the retention were studied as variable including pH of AB113; [P4VP-C16Br] dose, AB113 concentration and contact time between the copolymer and the used dye. At the optimal dose of [P4VP-C16Br] flocculant, the removal ratio of acid blue 113 could reach more than 98% in the pH range of 2-8. Furthermore, the flocculation process using [P4VP-C16Br] is a very fast process.
