- Abstract
Kewda ( Pandanus fascicularis Lam) essential oil was enriched with phenylethyl methyl ether (65-77%), terpinen-4-ol (13-18%) and α-terpineol (1-3%), which were definitely soluble in distillation condensate. The solubility of phenylethyl methyl ether, terpinen-4-ol and α-terpineol in water were more than 1000 ppm. Adsorption performance of single-solutes and multi-solutes over Amberlite-resins and Indion-resins were elucidated. XAD-4 and Indion 1014 MN-2 were most suitable because of their higher loading capacities of 2.2-3.2 mmol g−1 and 2.3-3.6 mmol g−1, respectively. Temkin adsorption isotherm was best fitted to the experimental results. Adsorption was followed Pseudo-second order, Ritche's-second order and Elovich's equation to validate the kinetics of chemisorption. Column breakthrough results revealed that the water soluble essential oil was recovered from the distillation condensate through a resin bed. Then the adsorbed solutes were desorbed from the resins with elution in ethanol to achieve complete recovery of high value essential oil from the distillation condensate. © 2015 Curtin University of Technology and John Wiley & Sons, Ltd.
