Mass Transfer Model for Extraction Process of L-Theanine across Bulk Liquid Membrane Containing Combined Carriers

Article Preview

Abstract:

This paper deals with the extraction of L-theanine containing Aliquat 336 and Di(2-ethylhexyl)phosphate(P204) as combined carriers and cyclohexane as solvent across bulk liquid membrane. A mathematical model of transport process was deduced, the forward and the backward interfacial reaction rate constants between the feed phase, the receiving phase and the membrane phase were taken into account. Using the experimental results, several parameters of the proposed model have been achieved by a nonlinear fitting method. It is a simply mathematical model which can be easily used to predict the concentration of the extraction process.
