首先对原料进行纯化操作，之后再进行酸化，高温煅烧以及钠化处理。本研究通过使用离子交换法制备出载银含量不同的的抗菌蛭石复合材料。通过设计正交试验，得出制备抗菌蛭石的最优实验参数，实验结果表明在溶液PH=5，CAgNO3=0.09mol/L，反应温度为50℃下反应5小时得到的抗菌蛭石的载银量最大，为3.14wt.%。通过对产物进行红外光谱分析，载银蛭石与纯化蛭石的红外吸收特征相似，并用大肠埃希菌对产品抗菌能力进行检测，实验结果证实产品具备很强的抗菌性且浓度越高杀菌率越高。 发自小木虫IOS客户端 |

Anti-bacteria composite vermiculites with varied Ag loads were prepared through ions-exchanged method. The optimum experiment parameters were obtained from orthogonal tests. The vermiculite Ag load, 3.14wt.%, was the largest when PH=5，CAgNO3=0.09mol/L，and T = 50℃ for 5h.. Ag-loaded vermiculites showed similar absorption characteristics with those purified in infrared spectroscopy analysis and had stronger antibacterial activities in test with E.coli., and the higher the load the higher the activity. |

| First, the raw materials were purified, then subjected to acidification, calcination under high temperature and charged with sodium. We used ion exchange method to prepare antibacterial vermiculite composite material with different amounts of silver loaded. By using orthogonal tests, we optimized the experimental parameters for the preparation of antibacterial vermiculite. The experimental results showed that the antibacterial vermiculite with the highest amount of silver loaded, 3.14wt.% was obtained in the reaction at pH=5, CAgNO3=0.09mol/L, temperature under 50 DEG C , and for 5 hours. The infrared spectroscopy analysis of the product showed that purified vermiculites with or without silver loaded were similar in absorption characteristics. The antibacterial ability was measured against Escherichia coli, the results suggest that the product has a strong antibacterial activity and the bactericidal rate was greater when the dosage was increased. |
