چکیده

Increasing demand and shortage of clean water sources due to the rapid development of industrialisation, population growth and long-term droughts have become an issue worldwide. Various contaminants are entering water resources from anthropogenic activities: from conventional pollutants, such as heavy metals and distillates, to emerging micropollutants, such as microcystins and antibiotics. Some of these pollutants could not be removed from water efficiently via conventional water treatment methods. Application of nanomaterials is considered as the fundamental method to more efficient wastewater treatment. Considerable attention was paid to fullerenes (C60), carbon nanotubes, quantum dots, metal oxides such as TiO2, ZnO, Fe2O3, Fe3O4, CuO, CeO2, SiO2 and Al2O3, and nanoparticulate metals such as Au, Ag, Co, and Ni. Among the nanoparticles, titanium dioxide (TiO2) nanoparticles are by far the most extensively studied metal oxide nanoparticles for water treatment. Based on studies, Nanotechnology holds great potential in advancing water and wastewater treatment to improve treatment efficiency as well as to augment water supply through safe use of unconventional water sources.

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.
