一种纳米银抗菌溶液及其制备方法
摘要：
一种纳米银抗菌溶液及其制备方法，涉及一种抗菌溶液，特别是涉及一种含有纳米金属银粒子和羧甲基壳聚糖的抗菌溶液及其制备方法。提供一种颗粒小、分布均匀、稳定性好、抗菌能力强和无毒副作用，含有纳米金属银粒子及羧甲基壳聚糖的纳米银抗菌溶液及其制备方法。为含有0.001～0.1mol/L的纳米金属银粒子及羧甲基壳聚糖的去离子水溶液。纳米金属银粒子的粒径最好为3～80nm。在含有0.001～0.1mol/L的纳米金属银粒子及羧甲基壳聚糖的去离子水溶液中加入2倍银离子摩尔浓度的水合肼还原剂，搅拌反应即可得到含有纳米金属银粒子和羧甲基壳聚糖的纳米银抗菌溶液。
摘要（英）：

The invention discloses a nano-silver antibacterial solution and a preparation method thereof and relates to an antibacterial solution, in particular to the antibacterial solution containing nano-metal silver particles and carboxymethyl chitosan and the preparation method thereof as well as provides a nano-silver antibacterial solution containing nano-metal silver particles and carboxymethyl chitosan and providing small particles, uniform distribution, good stability, strong anti-bacterial capacity and no toxic and side effects and a preparation method thereof. The nano-silver antibacterial solution is a deionized water solution containing nano-metal silver particles of 0.001-0.1 mol/L and the carboxymethyl chitosan, with the diameter of the nano-metal silver particle preferred to be 3-80nm. The deionized water solution containing nano-metal silver particles of 0.001-0.1 mol/L and the carboxymethyl chitosan is then added with hydrazine hydrate reductant with two times of silver ions molar concentration to be stirred and reacted to obtain the nano-silver antibacterial solution containing the nano-metal silver particles and carboxymethyl chitosan.
