Journal of Hazardous Materials, 138(2), 317-329.0304-38941873-3336https://doi.org/10.1016/j.jhazmat.2006.05.121https://www.sciencedirect.com/science/article/pii/S0304389406009642http://hdl.handle.net/11452/21687Reactive Green HE 4BD carrying polyamide hollow fibers were investigated as dye-affinity adsorbents for removal of chlorophenols (i.e., phenol. o-chlorophenol, p-chlorophenol and 2,4,6-trichlorophenol). Adsorption rates of chlorophenols were very high. Equilibrium was achieved in about 30 min. The applicability of two kinetic models including pseudo-first order and pseudo-second order model was estimated on the basis of comparative analysis of the corresponding rate parameters, equilibrium capacity and correlation coefficients. Results suggest that chemisorption process could be the rate-limiting step in the adsorption process. The maximum adsorption values of chlorophenols onto the Reactive Green HE 4BD carrying hollow fibers were 145.9 mu mol/g for phenol, 179.2 mu mol/g for 2,4,6-trichlorophenol, 194.5 mu mol/g for p-chlorophenol and 202.8 mu mol/g for o-chlorophenol. The affinity order was as follows: o-chlorophenol > p-chlorophenol > 2,4,6-trichlorophenol > phenol. The adsorption capacity of chlorophenols decreased with increasing pH. Desorption of chlorophenols was achieved using methanol solution (30%, v/v). The Reactive Green HE 4BD-carrying hollow fibers are suitable for repeated use for more than 10 cycles without noticeable loss of adsorption capacity.eninfo:eu-repo/semantics/closedAccessEngineeringEnvironmental sciences & ecologyChlorophenol removalPhenolHollow fibersPolyamideReactive green HE 4BDAdsorptionAquatic systemsAqueous-solutionActivated carbonOrganic pollutantsArticle0002423611000142-s2.0-33750302103317329138217018244Engineering, environmentalEnvironmental sciences
