چکیده
An amidoximated polyacrylonitrile copolymer was fabricated and structurally characterized as a heavy metals adsorbent. A copolymer of acrylonitrile (94%) and methylacrylate (6%) with average molecular weight of 100000 was used to produce the amidoximated adsorbent. Amidoximatedgroups were introduced to the prepared polyacrylonitrile by treatment with hydroxylamine - alcohol solution under reflux. The amidoximated polyacrylonitrile (APAN) adsorbent was characterized by FTIR, SEM and BET. The FTIR spectra indicated that the amidoximationreaction was successfully done. The SEM images showed that the particle size of the APANcopolymer beads became larger than the unmodified PAN copolymer beads. The surface area of the adsorbent before and after the amidoximation process was determined by BET. The surface area of the adsorbent has been decreased after modification with NH2OH∙HCl.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.
