dc.description.abstract
An electrochemical characterization of a polymer inclusion membrane (PIM) fabricated
with the ionic liquid (IL) Aliquat 336 (26%) and the polymer cellulose triacetate (CTA) (76%)
is presented. Considering the use of PIMs in separation systems to remove pollutants from
water, the characterization was performed with NaCl solutions by measuring membrane potential,
electrochemical impedance spectroscopy, and salt diffusion and results were compared with those
obtained from dry membranes. Results showed a significant reduction in the membrane diffusive
permeability and electrical conductivity as well as the transport number of cation Na+ across the
PIM when compared with solution values, which could be mainly related to the dense character
of the membrane. Membrane application in the separation of different sulfonamides (sulfathiazole,
sulfapyridine, sulfamethazine, and sulfamethoxazole) from water, with 1 M NaCl solution as striping
phase, was also considered. These results indicated that the different chemical characteristics of
the compounds, as well as the compact structure of the PIM, limited the transport of the organic
molecules though it
