摘要
采用溶(水)剂热法制备银系金属骨架化合物材料,利用X-射线衍射分析化学组成,以罗丹明B和亚甲基蓝为模型污染物测定不同银含量样品的光催化降解性能,通过生长曲线、最小抑菌浓度和抑菌环测试抗菌性能。结果表明:制备的化合物材料纯度较高,无杂质;0.2 g银系金属骨架化合物在可见光下的光催化活性最强,0.1 g金属骨架化合物对罗丹明B和亚甲基蓝溶液的降解率分别达到40%和82%;高浓度的化合物材料对大肠杆菌的抑制作用最强;在化合物浓度为62.50 mg/L的条件下,充足的反应时间可以完全抑制大肠杆菌生长。
Silver-based metal skeletal compounds were prepared by solvothermal method.Their chemical composition was analyzed by X-ray diffraction(XRD).The photocatalytic degradation performance of samples with different silver content was determined taking Rhodamine B and methylene blue as model pollutants.The antibacterial activity was tested by growth curve,minimum inhibitory concentration and inhibition zone method.The results showed that the prepared material had high purity without any impurity.The photocatalytic activity of 0.2 g silver-based metal skeletal compounds was the strongest under visible light.The degradation rates of rhodamine B and methylene blue solutions reached 40%and 82%,respectively,by adding 0.1 g silver-based metal skeletal compounds.High-concentration compound materials had strong inhibitory effect on Escherichia coli.When the concentration of the compound was 62.50 mg/L,the growth of Escherichia coli was completely inhibited in sufficient reaction time.
