Study on Antibacterial Properties of Blast Furnace Slag Containing Titanium
-
摘要: 以含钛高炉渣为原料,利用XRF、XRD、SEM、UV-Vis-DRS等分析方法对含钛高炉渣进行化学成分分析,确定了其作为光催化剂的可行性。通过抑菌环法和烧瓶振荡法研究了含钛高炉渣对白色念珠菌(ATCC10231)、大肠杆菌(ATCC25922)、金黄色葡萄球菌(ATCC6538)的抗菌性能。结果表明:纯含钛高炉渣对大肠杆菌(ATCC25922)无明显抑菌作用,对白色念珠菌(ATCC10231)抑菌作用表现不明显,而对金黄色葡萄球菌(ATCC6538)表现出一定抑菌性,在作用1 h时抑菌率达54.54%。Abstract: The blast furnace slag containing titanium(BFST) was characterized by XRF,XRD,SEM and UV-Vis-DRS to determine its feasibility as photocatalyst,and the antibacterial effects of BFST on candida albicans(ATCC10231),escherichia coli(ATCC25922) and staphylococcus aureus(ATCC6538) were investigated by inhibition zone and flask oscillation methods,respectively.The results show that BFST has no significant antibacterial effect on escherichia coli and candida albicans,while it can restrain the staphylococcus aureus to some extent with 54.54% of antibacterial rate for 1 h of action.
