| 摘 要： | 以水热法合成的炭微球为原料,经KOH活化制备了活性炭微球,通过在氯化铜溶液中浸渍使铜吸附在活性炭微球上,得到载铜活性炭微球.采用XRD、SEM、TEM、EDS、XPS和N2吸脱附对载铜前后活性炭微球的结构和形貌进行了表征,并测试了其抗菌活性.研究表明,活性炭微球表面负载的铜是以离子形式存在,并且随着溶液中铜离子浓度的增加,载铜量增大,氨水的加入可明显提高铜的负载量.抗菌结果显示,载铜活性炭微球对大肠杆菌(E.coli)和金黄色葡萄球菌(S.aureus)具有良好的杀灭能力.因此,它作为一种抗菌材料有望在水处理、气体过滤和微生物污染等方面获得应用.

| Abstract: | Carbon microspheres(CMs) were prepared via a hydrothermal method,and then activated with KOH to form activated carbon microspheres(ACMs).Copper-loaded activated carbon microspheres(Cu-ACMs) were obtained by the direct immersion in CuCl2 aqueous solution.The structure and morphology of ACMs and Cu-ACMs were characterized by XRD,SEM,TEM,EDS,XPS and N2 adsorption-desorption isotherms.The experimental results show that the copper valence state of Cu-ACMs samples is Cu2+ ion,and the amount of absorbed copper inc... |
