Aggregation of ions in higher permittivity solvents

Article Abstract:

It has been possible to measure electrolytic conductances of lithium 4-acyl-5-pyrazolonates and related salts in higher permittivity solvents at 25 degrees C. The lithium salt of the 4-benzoyl derivative showed a minimum in the conductometric curves in acetonitrile and acetone.

Contribution of Raman spectroscopy to the comprehension of limiting phenomena occurring with a vinylpyridinium anion exchange membrane during the electrolysis of Cr(VI) solutions

Article Abstract:

Raman spectroscopy has been used to investigate the transfer of chromate species through a vinylpyridinium anion exchange membrane. The presence of polychromate ions inside the AW11 membrane immersed in Cr(VI) solutions was identified.
