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 Cu 2+ ion, and the amount of absorbed copper increases with the increase of copper ion concentration in solution. The addition of ammonia can significantly improve the amount of absorbed copper. The antibacterial activities of asprepared materials measured indicate that the Cu-ACMs have the good activities to kill E. coli and S. aureus. Therefore, Cu-ACMs is a potential candidate as the antibacterial materials in some applications, such as water treatment, gas filtration and microbial contamination, etc.

Key words： activated carbon microspheres; copper; structure; antibacterial activity
