چکیده

Hydrogels were prepared by the free radical polymerization method successfully to remove textile dyes from the aqueous solution, due to the good properties of the hydrogels as being environmentally friendly, having a high ability to swell, high adsorption efficiency and good chemical stability. These hydrogels include surface SA-g-(PAAc-co-AM) hydrogel and its nanocomposite. The properties of the prepared hydrogels were studied using several techniques, including FESEM, TEM and XRD. Adsorption tests for these surfaces were performed on textile dyes including Brilliant green (BG), Methyl violate (MV), Malachite green (MG), Rhodamine B (RhB) and Brose Bengal (RB). We compared the surfaces of SA-g-(PAAc-co-AM) hydrogel, its nanocomposite and activated carbon (AC) as adsorbents. The best results of the percentage of removal (E%) of textile dyes were in the order of BG, RB, MV, MG and RhB. Arranging in the increasing order are as follows: SA-g-(PAAc-co-AM)/AC, SA-g-(PAAc-co-AM) and activated carbon (AC). The good results of the percentage of removal (E%) of SA-g-(PAAc-co-AM)/AC were also as follows: BG = ۹۸.۹۱, MG = ۹۳.۴۳, MV = ۹۰.۹۸, RhB = ۷۷.۵۵, RB = ۷۰.۶۶.

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.
