چکیده
A novel composite carbon molecular sieving membranes (CMSM) consisting of an activated carbon and phenolic resin, applicable to water treatment, was fabricated by carbonization and thermal deposition. The selectivities of these membranes are much higher than those typicallyfound with polymeric materials, and the selectivities are achieved without sacrificing productivity.In this study, the carbon molecular sieve membranes are made from activated carbon powdermixed with solution of novolac phenolic resin. The obtained material was dispersed by ultrasonic and pressed at two levels of high pressure and then raw disks are carbonized at 850 ̊C. The carbonization treatments were done on two kinds of carbon disks; with and without coating. The membranes were characterized using Scanning Electron Microscopy (SEM). The images revealed more uniform porous structure for the membranes produced at higher pressure.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
