摘　　要：以麦饭石为载体,在不同浓度、温度、交换时间条件下,采用恒温振荡法制备了以硝酸锌为抗菌成分的无机抗菌剂。结果表明,麦饭石对Zn2+的最佳吸附浓度、温度、交换时间分别为0.6mol/L、90℃、7h,最大吸附量为5.769μg/ml;麦饭石负载的金属离子浓度越大其抗菌性能越好型抗菌剂,最佳抑菌圈直径为35mm,最后对抗菌机理进行分析。Medicinal stone was used as the carrier of inorganic antibacterial agent.Under different conditions,such as the ion＇s concentration,exchange time and experiment temperature.It was prepared that the inorganic antibacterial agent,which was made up of zinc nitrate.The adsorption,phase,structure and antibacterial performance of prepared antibacterial agent was measured and analyzed by AAS,X-ray diffraction,IR spectrum,SEM and Bacteriostasis experiment.The result of this experiment about medicinal stone showed that the best absorb concentration,temperature and exchange time of Zn2＋ was 0.6mol/L,90℃ and 7h,respectively,and the max absorbance was 5.769μg/ml.Concentration of the mental ion which carried by medicinal stone was large,and antibacterial performance was good.When the diameter of bacteriostasis circle in in Zn-type antibacterial agent was 35mm,because of the mental ion in ion-carried medicinal stone,the result of XRD test showed that the distance of crystal face in green ore had a subtle change.
