MỘT SỐ YẾU TỐ ẢNH HƯỞNG ĐẾN QUÁ TRÌNH HẤP PHỤ KHÁNG SINH STREPTOMYCIN TRONG MÔI TRƯỜNG NƯỚC CỦA VẬT LIỆU COMPOSITE POLYAMIDE-6/GRAPHENE OXIDE/ 3-AMINOPROPYLTRIETHOXYSILANE

Tóm tắt

In this study, PGA composite material was synthesized using the solution blending method. The structural
characteristics of the material before and after STM antibiotic adsorption were analyzed using scanning
electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX), revealing significant changes
in morphology and chemical composition after the adsorption process. The study was conducted under
various conditions, including pH, adsorbent mass, and temperature, to determine the factors influencing
adsorption efficiency. Experimental results identified the optimal adsorption conditions at an adsorbent
mass of 0.1 g, a pH of 7, and demonstrated that the adsorption process is endothermic.The studied results
showed that PGA composite material exhibited effective adsorption capacity for STM antibiotics, suggesting
potential applications in addressing environmental pollution caused by antibiotic residues.
