| Abstract: | ABSTRACTThe aim of this work was to obtain and characterize the selectivity of a new type of ion-exchanger – porous highly basic monolith with high internal phase emulsion (HIPE) structure. Poly(HIPE)ViM monolith of bis-vinylimidazolium salts was prepared in a water-in-oil-in-water emulsion (W1/O/W2). The structure of the resulting HIPE polymer was confirmed using scanning electron microscopy (SEM). Ion-exchange ability and the selectivity of monolithic anion-exchanger were tested towards the following inorganic anions: F?, Br, Cl?, NO3?, SO42-, Mo7O246-, PO43-; and organic anions: malate, citrate, malonate, tartate, lactate and oxalate. The concentration of anions before and after the sorption was measured using ion chromatography. |
