【 摘 要 】

This study explores the potential of using PEBA as a sorbent for removing phenolic compounds from wastewater. The sorption isotherms of phenol, 4-chlorophenol (4-CP), 4-nitrophenol (4-NP), 4-methylphenol (4-MP) and catechol from their respective single solute solutions were studied based on the Linear, Langmuir and Freundlich models. The Freundlich model was shown to be suitable to represent the equilibrium sorption of all the phenolic compounds in the PEBA sorbent, and the sorption capacity of these phenolic compounds in PEBA is in the order: catechol
