In order to study the influence of glucose and urea on the I-125 transport
across an anion exchange paper membrane. the transmembrane potential. the f
luxes. and the concentrations of I-125, glucose and urea within the membran
e were measured in the Na I-125 concentration-cell system containing glucos
e or urea. Glucose and urea increased the membrane/solution distribution of
the iodide ion, but scarcely affected the diffusion process of iodide: ion
within the membrane. (C) 2001 Elsevier Science Ltd. All rights reserved.
