a
Measured thickness (using a micrometer screw gauge) prior analysis. Note: ‘α’ is permselectivity. ‘δ’ is thickness; ‘SD.’ is swelling degree; ‘IEC’ is Ion exchange capacity, ‘ta(−)’ is transport number (of the Cl− Ion) in the membrane. Ud,d is the diffusate dialysis coefficient (for H+ ions) and ‘S’ is the separation factors.
