Preparation and electrochemical characterizations of cation-exchange membranes with different functional groups

Preparation and characterization of monovalent cation selective sulfonated poly(ether ether ketone) and poly(ether sulfone) composite membranes

“…The magnitude of the membrane potential depends on the electrical characteristics of the membrane in addition to the nature and concentration of electrolyte solutions used [32,33]. Membrane potential [( φ) I =0 ] data were recorded using different membranes in electrolyte solutions such as NaCl(aq), CaCl 2 (aq), MgCl 2 (aq) and CuCl 2 (aq) with 0.055 mol dm −3 mean concentration.…”

Preparation and characterization of N-methylene phosphonic and quaternized chitosan composite membranes for electrolyte separations

“…Thus in all cases acidic or basic (H + or OH − form) ion-exchange capacities were determined [23]. For determining IEC, membrane samples of known weight were equilibrated either in 1.0 M HCl or in 1.0 M NaOH solutions for 24 h to ensure that all charged sites of the membrane were either in H + or OH − form.…”

Sharp decline in counter-ion transport number of electrodialysis ion exchange membrane on moderate increase in temperature

“…Variation of CTN with pH [9,10] as well as change in CTN on changing salt [11,12] is commonly reported.…”
