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
High molecular weight PPO was brominated to three levels of degree of bromination. Each brominated PPO was further sulfonated to three levels of degree of sulfonation. Membranes were prepared from these sulfonated brominated PPO (SPPOBr) and the transport properties of CO 2 , CH 4 , O 2 , and N 2 ga
The reverse osmosis performance of thin-film composite membranes prepared from sulfonated polyphenylene oxide polymer with different ion-exchange capacities was studied using various electrolyte solutes. The effect of the solvent used for the preparation of the polymer solution for surface coating w
Thin film composite membranes were prepared by coating a thin layer of sulfonated poly ( 1,4dimethyl-2,6-phenylene oxide) polymer on the surface of a polysulfone ultrafiltration membrane. The membrane performance was studied when the sulfonate was either in the hydrogen form or loaded fully with an
