摘要:

以Bi(NO3)3·5H2O和Al(NO3)3·9H2O为原料,溶解在乙二醇中形成乙二醇铋配合物前驱体,在不同的温度下微波加热合成不同形貌的纳米铝酸铋凝胶.通过电感耦合等离子体发射光谱(ICP)、粉末X-射线衍射(XRD)、扫描电子显微镜(SEM)、ZATA电位等分析测试手段,对所得产物进行表征,并且考察反应温度和微波辐照时间对产物成分与粒径的影响.结果表明,产物为密集球状颗粒,在微波加热4 min条件下粒径平均为30 nm.实验得到的纳米颗粒对大肠杆菌表现出明显的抗菌性能.

Abstract:

Nanosized bismuth aluminate gel particles were synthesized through the reaction of Bi(NO3)3·5H2O and Al(NO3)3·9H2O dissolved in ethylene glycol at different temperatures with the microwave heating.Analytical methods such as ICP,SEM,XRD and ZATA potentiometer were used to characterize the obtained gel particles.The effects of reaction temperature and microwave irradiation time on the composition and particle size of the obtained particles were investigated.The results showed that bismuth aluminate synthesized in ethylene glycol was dense spherical particles with a diameter of about 30 nm.The obtained gel particles show significant antibacterial properties against escherichia coli..

Key words: microwave heating, bismuth aluminate, nanosized gel particles, escherichia coli., antibacterial property
