| 中文摘要 | the goal of the present work is the development of nanofiltration membranes by the phase inversion technique using a newly developed polymer, cardo poly(arylene ether sulfone) with pendant tertiary amine groups (pes-ta). the obtained membranes were characterised in terms of their water flux, salt and basic dye rejections, the cross-sectional and surface morphologies, surface charge characteristic, and chlorine tolerance. a typical membrane (m-40) exhibited moderate rejection to salts (36.6% to nacl, 63.3% to mgcl(2) and 70.2% to fecl(3)), but high rejection to basic dyes (>98%). zeta potential measurements indicated that the pes-ta membranes were positively charged below ph 10.7. the m-40 membrane showed excellent chlorine tolerance. after exposure to an aqueous naocl solution (active chlorine concentration >= 1000 ppm) for 20 days, the rejection of membrane was not changed. in addition, the obtained membrane showed efficient separation of basic dyes in the presence of nacl salt.
