摘要: Abstract Polysulfone electro-spun nano-fibrous membranes (PSU ENMs) were prepared using a mixture of solvents N , -dimethyl formamide (DMF) and tetrahydrofurane (THF) for microfiltration ultrafiltration. The involved electro-spinning parameters, namely, the polymer solution flow rate, electric voltage distance between needle tip collector varied in range within which it was possible to obtain bead-free PSU ENMs. Their effects on morphology structure ENMs studied. Interfacial polymerization technique applied develop novel thin-film composite polyester-PSU based characterized by means different techniques such as scanning electron microscopy, contact angle measurements, X-ray diffraction, attenuated total reflectance Fourier transform spectroscopy. Micro/ultra-filtration tests conducted humic acid model solutions with concentration 15 mg/L at two pH values (3 11). It observed that not selective under acidic conditions, whereas achieved better separation factors lower irreversible fouling than those un-modified
