Polyelectrolyte complex membranes made of chitosan–PSSAMA for pervaporation separation of industrially important azeotropic mixtures
Journal of Industrial and Engineering Chemistry(2019)
Abstract
•Water/ter-butanol mixture show highest flux compare to other azeotropic mixtures.•Total flux and flux of water are overlapping suggest the PECMs are water selective.•Membrane containing 9 mass% of PSSAMA showed the highest separation selectivity.•The negative ΔHs values indicated that Langmuir’s mode of sorption is predominant.
