Currently, exchanging trends in the expensive usage of ceramic materials such as alumina, zirconia etc. into economical ceramic raw sources have been studied extensively over the last decade for various technological applications. Despite the fact that this ceramic compound or elements offer a great performance and stability, especially at high temperature and corrosive or acidic conditions, th...
The special channels and intrinsic defects within GO laminates make it a very potential candidate for gas separation in recent years. Herein, the gas separation performance of GO membranes prepared on the surface of ceramic α-Al2O3 hollow fiber were investigated systematically. The microstructures of ceramic hollow fiber supported GO membranes were optimized by adjusting operation conditions. A...
This study focuses on the preparation and modification of a thin-film composite (TFC) hollow fiber polyamide membrane fabricated by the interfacial polymerization of Piperazine (PIP) and trimesoyl chloride (TMC) on a porous polysulfone substrate. The effects of triethylenetetramine (TETA) and silica nanoparticles (SiO2) contents in the aqueous phase (as the additives) on the morphology and perf...
Hollow fiber membrane contactors have been applied in various industries e.g. chemistry, petroleum, biotechnology and medicine. They are also widely used in artificial organs e.g. artificial lung, kidney and liver as well as some pharmaceutical procedures such as separation and purification of biological materials. Intrinsic properties of hollow fiber membranes, such as high packing density and...
In this study, polyphenylsulfone (PPSU) hollow fiber membrane was fabricated via a wet spinning method with the addition of ethylene glycol (EG) in the range of 0-10 wt% as the additive. The EG was added to improve the membrane pore formation and interconnectivity for better membrane contactor performance in extracting and removing the free fatty acid (FFA) from crude palm oil (CPO). Four diffe...
in this study, the influence of the salts as an additive on the performance of the membrane was investigated and an extensive work was performed to optimize pvdf hollow fiber membranes through a response surface methodology (rsm). the prepared membranes were characterized by sem, contact angle and lep measurement. then, the rsm was used for the optimization of surface pore size, porosity and hy...

In the Introduction section of this Research Article, description on membrane geometry was incorrect. The first sentence fourth paragraph in section, “Herein we prepared high-silica CHA zeolite membranes ceramic hollow fiber substrates for Kr/Xe separation.” should be revised to read disk This change does not affect interpretation data and conclusions, but guarantees a consistent with other sec...
