چکیده
Activated carbon (AC) is the most efficient adsorbent used for pollutant removal due to itslarge surface area, well-developed pore structure, high-speed adsorption and thermal andchemical stability [۱]. Silver nanoparticles (AgNPs) have attracted significant attention due totheir remarkable properties and diverse applications. They are important antibacterial materialsas an effect of their larger surface areas in comparison to the bulk material. Researches haveshown that silver nanoparticles, silver ions, and nano silver-containing complexes haveantimicrobial behavior with a high ability to inactivate bacteria and viruses [۲, ۳]. However,conventional synthesis methods often involve the use of toxic chemicals and generateenvironmental concerns. This work investigates the preparation and characterization of activatedcarbon from semecarpus anacardium nutshell by KOH activation. In this study also, we present agreen synthesis approach for fabricating Ag Nano particles on ACs using starch and glucose asnovel materials for stabilizing and reducing agents, respectively.Transmission ElectronMicroscopes (TEMs) images confirm the particle size distribution of the silver nanoparticlesmainly in the range of ۱–۵ nm.The synthesized AgNPs were characterized for their physicochemical properties, includingmorphology, particle size distribution, and surface chemistry. The environmentally friendlysynthesis method demonstrated the potential for large-scale production of silver nanoparticleswith enhanced stability and reduced environmental impact. The study also highlights the diverseapplications of green-synthesized AgNPs in various fields.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.
