中文摘要：

针对含银离子无机抗菌剂的变色问题,研究了以海泡石为载体,银离子（Ag＋）和锌离子（Zn2＋）为抗菌成分,制备双离子型无机抗菌剂的工艺方法。通过原子吸收光谱检测海泡石所载抗菌离子的含量,对海泡石吸附Ag＋及Zn2＋的工艺条件进行了研究,并对所制银锌/海泡石进行了抗菌性和耐变色性测试和观察。结果表明,在本文实验条件下,当吸附溶液中的Zn2＋与Ag＋初始浓度摩尔比为10∶1时,海泡石所载的这两种抗菌离子的质量比也为10∶1以上,达到了增大海泡石载Zn2＋量,减少其载Ag＋量的目的。所制备的银锌/海泡石有良好的抗菌性和耐变色性。

英文摘要：

In order to prevent silver ion contained inorganic antibacterial from discoloring,a technique for preparing dual-ion inorganic antibacterial agent was researched,in which the sepiolite was taken as a carrier,and the silver ion（Ag＋） and the zinc ion（Zn2＋） were taken as antibacterial constituents.By using the atomic absorption spectrum to test the amount of antibacterial ions carried by the sepiolite,the technological conditions for the sepiolite to adsorb Ag＋ and Zn2＋ were studied,the antibacterial performance and discoloration resistance of prepared silver-zinc/sepiolite were also observed and tested.The results demonstrated that under the experimental conditions,when the mole ratio of initial concentration of Zn2＋to Ag＋ in adsorption solution is 10∶1,the mass ratio of the two antibacterial ions carried by sepiolite is also larger than 10∶1,so the original purposes to increase the volume of Zn2＋ and decrease the volume of Ag＋carried by sepiolite are achieved.The prepared silver-zinc/sepiolite is proved that it has remarkable antibacterial performance and discoloration resistance.
