Recovery of Model Pharmaceutical Compounds from Water and Organic Solutions with Alginate-Based Composite Membranes.

ABSTRACT: In this work, we combined the non-solvent induced phase separation (NIPS) and further cross-linking by cations towards the preparation of nanofiltration membranes based on sodium alginate, a biodegradable, natural polymer. Acetone, ethanol, toluene, and hexane were used as non-solvents, and cations of calcium, silver, and aluminum-for polymer cross-linking, respectively. Results showed the precipitation strength of non-solvent played a noticeable role in the membrane's performance; for instance, the toluene permeability changed by four orders of magnitude with the decrease of precipitation strength of the non-solvent: acetone (Ptoluene = 0.1 kg∙m-2∙h-1∙bar-1) < ethanol (3 kg∙m-2∙h-1∙bar-1) < hexane (41 kg∙m-2∙h-1∙bar-1) < toluene (415 kg∙m-2∙h-1∙bar-1). It was shown that simultaneous preci
