Adsorption and adsorptive separations: A review and bibliographical update (1994)

Abstract

This paper provides a review of the 1994 journal literature and complete bibliography concerned with adsorptive separations. The references are taken from the 45 most important chemical engineering journals. This paper provides an update to the literature as provided in previous bibliographic papers 1995). References for membranes and membrane-type separations (for 1992-1993) were the subject of a separate bibliographic paper (Ray 1994), due to the number of papers now published on this topic each year. A review and bibliography paper covering 1994 for membranes has been submitted for publication. Bibliographic papers covering traditional unit operations (Ray 1992;1993; and supercritical extraction (Ray 1994) have been published. A bibliography of the chemical engineering journal literature from 1967-1988 has been published by the author (Ray 1990), and can provide access to a wider range of topics. A complete bibliographic listing of the chemical engineering journal literature from 1989 to 1994 (with subsequent six-monthly updates) is available on a CD-ROM database (Published by Royal Melbourne Institute of Technology) and full details can be obtained from the author.

Kinetics and equilibrium studies of malachite green adsorption on rice straw-derived char

“…Many studies have shown that the boundary-layer diffusion is the rate controlling step in systems characterized by dilute concentrations of adsorbate, poor mixing, and small particle size of adsorbent. Whereas the intraparticle diffusion controls the rate of adsorption in systems characterized by high concentrations of adsorbate, good mixing, and big particle size of adsorbent [26,27]. Also, it has been noticed in many systems that boundary-layer diffusion (external mass transfer) is dominant at the beginning of adsorption during the initial adsorbate uptake, then gradually the adsorption rate becomes controlled by intraparticle diffusion after the adsorbent's external surface is loaded with the adsorbate [25][26][27].…”

Piecewise linear regression: A statistical method for the analysis of experimental adsorption data by the intraparticle-diffusion models

“…Many studies have shown that the boundary layer diffusion is the rate controlling step in systems characterized by dilute concentrations of adsorbate, poor mixing, and small particle size of adsorbent [2,3]. Whereas the intraparticle-diffusion controls the rate of adsorption in systems characterized by high concentrations of adsorbate, vigorous mixing, and large particle size of adsorbent.…”

“…Whereas the intraparticle-diffusion controls the rate of adsorption in systems characterized by high concentrations of adsorbate, vigorous mixing, and large particle size of adsorbent. Also, it has been noticed in many systems that film diffusion (external mass transfer) is dominant at the beginning of adsorption during the initial adsorbate uptake, and then the adsorption rate becomes controlled by intraparticle-diffusion after the adsorbent's external surface becomes loaded with the adsorbate [1,2].…”
