摘　　要：目的:考察自制纳米银溶液的稳定性。方法:以纳米银溶液的外观性状、紫外最大吸收波长、纳米银粒径、纳米银含量为考察指标,考察了温度、光线、pH等对稳定性的影响,并进行了长期稳定性试验。结果:冷冻、强光、低pH值可使纳米银稳定性降低,室温下可稳定至少2年。结论:纳米银溶液对强光、冷冻、酸不稳定,对热较稳定。纳米银溶液应避光、避冻,中性或弱碱条件下存放。OBJECTIVE To examine stability of homemade nano silver solution.METHODS Appearance,maximum absorption wavelength of ultraviolet,grain size and silver content were used as test items to study influence of temperature,light and pH values on stability of nano silver solution.Long term stability experiment was also performed.RESULTS Stability of nano silver solution can be decreased under circumstances of freeze,strong light and low pH.It can remain stable at room temperature for at least two years.CONCLUSION Nano silver solution is unstable to strong light,freezing and acid,and relatively stable to heat.It should be stored under neutral or weak alkaline conditions,and avoid light and freezing.
