چکیده

In recent years, surface functionalised materials have attracted considerable interest as adsorbent agents in water purification. Although surface modification of materials using wet chemistry routes has previously been employed for water purification, applying plasma polymerizations technology in this field appears to be a more cost-efficient and effective alternative. In this novel technology, an organic monomer gas containing specific functional groups is excited into the plasma state within a rotating plasma reactor containing substrate particles. The monomer is fragmented into active species via plasma state interactions and is deposited on all surfaces within the reaction chamber. In water, some functional groups are negatively charged, while others are charged positively. Therefore, by choosing the appropriate functional groups for polymerization, both anionic and cationic pollutants can be removed via electrostatic attractions. This article begins with reviewing the basic concepts of nano-thin film manufacturing using plasma polymerization technology and continues with reviewing the potential application of this technology in developing a new class of adsorbent materials for water purification.

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.
