Brief content The overall objective of our research was to investigate the use of hydrophobic adsorbents in the separation of 1-phenylethanol (1-PE) and acetophenone (AP) mixtures. Our research started with a group of 17 commercial hydrophobic adsorbents from two major world producers. In order to evaluate their capacities for 1-PE/AP and the selectivity, batch adsorption experiments were carried out using single-component and binary aqueous solutions, respectively. A broad range of concentration values and different ratios of l-PE and AP were used in these experiments to determine single-component and binary adsorption isotherms for selected adsorbents. Competitive Langmuir adsorption isotherm was used for description of all adsorption equilibrium data. We also investigated correlation between selectivity/maximal adsorbed amount and specific surface area of adsorbents.
