Pervaporation separation of water-ethanol was carried out with polyion complex membranes based on k-carrageenan. The polyion complex membranes were prepared by the ion complex formation between k-carrageenan (anionic polymer) and poly{ 1,3-bis[4-alkylpyridiniumlpropane bromide } s (cationic polymers
