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%。
Titanium-bearing blast furnace slag was used as raw material, and chemical composition analysis of titanium-bearing blast furnace slag was carried out by XRF, XRD, SEM and UV-Vis-DRS. The feasibility of photocatalyst was confirmed. The antibacterial activity of titanium-bearing blast furnace slag against Candida albicans (ATCC10231), Escherichia coli (ATCC25922) and Staphylococcus aureus (ATCC6538) was studied by means of bacteriostasis method and flask shaking method. The results showed that the pure titanium-bearing blast furnace slag had no significant bacteriostasis against Escherichia coli (ATCC25922), no obvious inhibitory effect on Candida albicans (ATCC10231), and no antibacterial activity against Staphylococcus aureus (ATCC6538) The inhibitory rate reached 54.54% at 1 h.
