Sulfonated polyethersulfone/sulfopropyl methacrylate membranes impregnated with the polysulfopropyl acrylate coated ZnO nanoparticles were developed using a non-solvent-induced phase separation recipe. The composite offered much-enhanced hydrophilicity and improved porosity, which are critical for excellent antifouling performance high permeate flux. By adding modified ZnO, it achieved maximum ...

A sulfonated polyethersulfone (SPES)/polyethersulfone (PES) blend catalytic membrane was prepared and used as a heterogeneous catalyst in the esterification of the acidified oil (acid value 153 mg KOH/g) with methanol for producing biodiesel. The results showed that the free fatty acids conversion reached 97.6% using SPES/PES catalytic membrane under the optimal esterification conditions. Meanw...

Polyethersulfone-sulfonated polyethersulfone (PES-SPES)/NaY zeolite/nylon sandwich structure membranes were prepared and used to adsorb Cu2+ from water. The adsorption kinetics, isotherm, dynamic experiment, reusability discussed. experimental data showed that the Langmuir isotherm model, Dubinin–Radushkevich (D-R) pseudo-first-order kinetic model can well represent of on membrane, indicating a...

Separation performances of micellar enhanced ultrafiltration process in Cr(III) and Cr(VI) removal has been evaluated. The neat as well as sulfonated and aminated derivatives of polyethersulfone were tested as the material for membrane preparation while hexadecylpyridine chloride and sodium dodecyl sulfate served as surfactant. It was shown that modified membranes can better reject both forms o...

Metal nanoparticles are known as highly effective catalysts although their immobilization on solid supports is frequently required to prevent aggregation and to facilitate the catalyst application, recovery, and reuse. This paper reports the intermatrix synthesis of Pd0 nanoparticles in sulfonated polyethersulfone with Cardo group membranes and their use as nanocomposite catalytic membrane reac...

In this work membrane (proton exchange membrane) by using the blend polymers (polyethersulfone (PES), Expandable polystyrene (EPS), polyvenylidinefluride polymer (PVDF)) were prepared. This was modified adding organic sulfonic acid to solution precasting process, and sulfonated dipping it in diluted sulfuric (H2SO460%) post casting process. The sulfonation confirmed via FTIR spectra. characteri...
