The ultrasound assisted green synthesis method was investigated to produce an antibacterial adsorbent for levofloxacin removal from wastewater. The effects of AgNO₃/corncob extract ratio, reaction time and US power on synthesis of AgNPs were evaluated. The optimum conditions for the synthesis of silver nanoparticle having the maximum yield were obtained (AgNO₃/corncob extract ratio: 1:1 v/v, reaction time: 35 min. US power: 46 W). Silver nanoparticles were synthesized by using corncob extract as reducing agent and deposited to activated carbon under sonication. The specific surface area of silver nanoparticle attached activated carbon increased 33% compared to that of activated carbon due to the pore development effect of ultrasound irradiation. The superior adsorption capacity of silver nanoparticle attached activated carbon can be attributed to its large specific surface area (1842.62 m²/g) and average pore diameter (1.18 nm). The adsorption of levofloxacin to activated carbon or silver nanoparticle attached activated carbon showed the best correlation with Langmuir isotherm and pseudo-second order kinetic model.

研究了超声辅助的绿色合成方法，以生产用于从废水中去除左氧氟沙星的抗菌吸附剂。评估了AgNO ₃ /玉米芯提取率，反应时间和US power对AgNPs合成的影响。获得了具有最大产率的合成银纳米粒子的最佳条件（AgNO ₃/玉米芯提取物比率：1：1 v / v，反应时间：35分钟。美国功率：46 W）。以玉米芯提取物为还原剂合成了银纳米颗粒，并在超声处理下沉积在活性炭上。由于超声辐射的孔发展作用，与活性炭相比，附着有银纳米颗粒的活性炭的比表面积增加了33％。附着有银纳米颗粒的活性炭的优异吸附能力可以归因于其大的比表面积（1842.62 m ² / g）和平均孔径（1.18 nm）。左氧氟沙星在活性炭或附着有银纳米颗粒的活性炭上的吸附表现出与Langmuir等温线和拟二级动力学模型的最佳相关性。
