P. Harriott et Sv. Ho, MASS-TRANSFER ANALYSIS OF EXTRACTION WITH A SUPPORTED POLYMERIC LIQUID MEMBRANE, Journal of membrane science, 135(1), 1997, pp. 55-63
Supported polymeric liquid membranes with polypropylene glycol as the
liquid phase were tested for extraction of p-nitrophenol from an aqueo
us wastestream. Transient experiments with small flat sheet membranes
were used to determine the membrane permeability and the diffusion coe
fficient in the liquid phase. The process was then scaled up using hol
low-fiber radial-flow modules, first in the laboratory and then under
plant conditions. When boundary layer resistance and membrane accumula
tion and depletion were allowed for, the results obtained were consist
ent with predictions based on the data for flat sheets.
