摘要：

The permeation of chromium (III) using pseudo-emulsion based hollow fiber strip dispersion (PEHFSD) technology and the quaternary ammonium salt trioctyl methylammonium chloride (TOMACl) dissolved in n-decane as mobile carrier has been investigated. Factors affecting chromium permeability, such as hydrodynamic conditions, carrier concentration in the organic phase, metal and NaOH concentrations in the feed phase, etc., have been analyzed. The value of the overall permeation coefficient obtained under standard experimental conditions was 4.0 x 10(-4) cm s(-1). Mass transfer modelling was performed and the aqueous and membrane resistances were estimated as 1066 and (1.7-17) x 10(3) s cm(-1), respectively. (C) 2009 Elsevier B.V. All rights reserved.
