Conductivity of PVOH films


Measure the conductivity of a PVOH film crosslinked with glutaraldehyde (see 9/14/12 for procedure) at different time intervals.


cell constants: 0.4663 (orion versa star) 0.479 (orion 5 star)

The following solutions were used on either side of the film

  • ion solution of 100ppm Cl-, 100ppm Br-, 100ppm SO4 2- (as Na+ salts)
  • HPLC grade water
