There is a huge stock of titanium-containing blast furnace slag in China with high added value.In order to achieve comprehensive utilization of titanium-containing blast furnace slag,in response to the high titanium component content in titanium-containing blast furnace slag,with the modi-fied titanium-containing blast furnace slag used as raw material,the composition of modified titanium-containing blast furnace slag is determined through XRF,XRD,SEM and other analysis methods,and its feasibility as an antibacterial material is confirmed.The antibacterial property of modified titanium-containing blast furnace slag against Escherichia coli(ATCC25922)is separately measured with the oxford cup method,drilling method and patch method.The results show that the modified titanium-containing blast furnace slag has antibacterial property.The solid phase synthesis method with a V2O5 doping ratio of 15％has the most obvious antibacterial effect on Escherichia coli(ATCC25922).
