Thin film composite membranes of sulfonated poly(phenylene oxide) (SPPOk-polysulfone (PS) (SPPO-PS) were prepared by coating the hydrogen or sodium form of SPPO onto various porous substrates such as polysulfone (PS). The effects of membrane preparation conditions and feed water variables on the sal

Novel membranes based on sulfonated poly (phenylene oxide) (SPPO) was developed. SPPO membranes in the hydrogen form were converted to metal ion forms. The effect of exchange with metal ions including monovalent (Li ฯฉ , Na ฯฉ , K ฯฉ ), divalent (Mg 2ฯฉ , Ba 2ฯฉ , Ca 2ฯฉ ) and trivalent (Al 3ฯฉ ) ions was
