چکیده
The free radical method was used for the synthesis of hydrogel, relying on environmentally friendly and available monomers such as acrylic acid (AC) and acrylamide (AM) in the presence of (CdS). The application of (AC-co-AM)/CdS hydrogel nanocomposite for the removal of Cypermethrin Pesticides (CYP) shows wide potential; as highly efficient absorbents for treating water contaminated with CYP under ideal conditions. The most important factors affecting the adsorption process, such as equilibrium time and hydrogel dosage, were studied. Optimal conditions for insecticide removal were found to be pH ۹.۰, equilibration time = ۱۵۰ min, hydrogel weight = ۰.۱ g, concentration = ۱۰ mg L −۱. Temperature had a strong effect on the biosorption process. Moreover, the hydrogel was characterized by FESEM, TEM and XRD. Increased weight of hydrogel nanocomposite results in increase removal percentages; ۰.۱ g/L of weight of hydrogel resulted in ۸۱.۳۳۳ % absorption. The pH solution increased, with removal percentage of pH =۲ (۴۱.۵۵ %) to pH=۱۱ (۸۹.۷۸%) increased. (AC-co-AM)/CdS hydrogel nanocomposite surface has a very high efficiency in regeneration and use, so that it is characterized by its stability and high stability compared to (AC-co-AM) hydrogel, so that it is characterized Stability of ۵ cycles (۸۱.۶۷% to ۷۰ .۲۲%). Overall, the present study suggests that this environmentally friendly, effective and low-cost hydrogel may be useful for removing insecticide from aqueous solution.کلیدواژه ها

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.
