چکیده

Due to its importance water, a lot of research has been done in the field of nanotechnology for water purification. In this study, Nd-TiO2/PEG/bentonite nanocomposit was synthesized by three chemical compounds that had adsorption property. Microstructure of synthesis nanocomposite was investigated by XRD, SEM and FT-IR. The removal process of Cu2+ was performed by flotation of nanocomposite in the bulk of sample. The effective parameters were investigated in removal process, such as: removal time, sample volume, amount of nanocomposite, pH and etc. The concentration of selected ion was monitored by using a flame-atomic absorption spectrometer. In the optimized condition, effect of interference ions was studied and according results, no evidence of interference was observed. The photocatalytic activity of Nd-TiO2/PEG/bentonite nanocomposite will investigate under visible light irradiation.

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.
