摘要:
A series of composite forward osmosis (FO) hollow fiber membranes were developed using, interfacial polymerization (IP) on the lumen side of copoly(phthalazinone biphenyl ether sulfone) (PPBES) substrates. The effect of the PPBES substrate and IP preparation conditions on composite FO membranes performance was evaluated. Water flux of the FO membranes increased with an increase in flux of PPBES substrates. The IP preparation parameters such as solvents, monomer concentrations, reaction time, and curing conditions had a great influence on the properties of composite FO membranes. The novel PPBES composite FO hollow fiber membranes exhibited high thermal stability. The water flux of composite FO membranes improved from 24.0 L/m(2) h to 66.5 L/m(2) h without significant change of Js/Jv ratio when the draw solution temperature was elevated from 23 degrees C to 85 degrees C.
