G. Arana et al., Permeation of mixtures of four phenols through a supported liquid membranein NaCl 1.0 mol center dot dm(-3) medium, SEP SCI TEC, 34(4), 1999, pp. 665-681
The permeation of four phenols (phenol, 2-chlorophenol, 2-nitrophenol, and
2,4-dichlorophenol) through a supported liquid membrane has been studied in
NaCl 1.0 mol.dm(-3) medium. The flux of each phenol was determined by meas
uring in real time the change of their concentration in the strip phase by
making use of a fiber optic spectrophotometer and a multivariate calibratio
n. The model for the permeation of phenol alone was first developed by maki
ng permeation experiments of a phenol, and then permeation studies of the m
ixture were carried out and the model was extended to those phenols. It was
found that the permeation of a phenol is interfered with by the presence o
f other phenols.
