Abstract:
In this research, the conductivity (κ) of carboxymethyl cellulose (CMC)
solutions of different concentrations and chains length was studied at
various temperatures. κ was found to increase with increasing
concentration, temperature, and decreasing the chain length of CMC. The
activation energy (Eκ) of the different solutions was estimated according to
the Andrade equation, Eκ was increased with increasing concentration and
decreasing the chain length of CMC. The results indicated that solute –
solute contact is decreased and the solute-solvent interaction is increased in
CMC solutions with increasing temperature and decreasing chain
dimensions of CMC.
