Modeling and kinetics study of conventional and assisted batch solvent extraction

Batch solvent extraction techniques have been widely explored. On understanding its potential significance, this article aims to review kinetics and modeling of various extraction techniques which involve assisted means including microwave-assisted extraction (MAE), ultrasonic-assisted extraction (UAE), pulse electric field (PEF) and high voltage electrical discharge (HVED). This review includes a detailed discussion of the instrumental setup, extraction mechanisms and their distinct advantages and disadvantages. Additionally, the impact of the operating parameters on the extraction kinetics of the mentioned techniques are highlighted. The review also covers the mathematical modeling based on Pick's law, chemical rate law and empirical models. The established kinetic models of various extractions are also summarized to facilitate better understanding. (C) 2013 The Institution of Chemical Engineers. Published by Elsevier B.V.
