中文摘要:
      建立单颗粒-电感耦合等离子体质谱法(Single particle ICP-MS,SP-ICP-MS)测定纳米抗菌商品中纳米银颗粒(Silver nanoparticles, AgNPs)粒度分布的方法。首先采用微波消解-ICP-MS法测定了纳米抗菌商品中的总银含量,确定样品稀释倍数。然后在SP-ICP-MS模式下,测定三种AgNPs标准样品(30 nm、50 nm和80 nm)的粒径,所得结果与供应商提供的TEM值接近,说明SP-ICP-MS法能够准备表征水溶液中AgNPs的粒径分布,同时采用SP-ICP-MS测定了纳米抗菌商品中纳米银颗粒粒径分布。该方法简单快速、灵敏度高,能够为纳米抗菌材料中AgNPs表征提供准确的表征方法。
英文摘要:
      A method based on single particle ICP-MS was developed to the characterization of size distribution of the silver nanoparticles (AgNPs) in nano-antibacterial consumer products. Firstly, the total silver content in consumer products was detected using microwave digestion to make sure the dilution ratio of consumer products for the characterization of size distribution of AgNPs. Then the SP-ICP-MS method was used to detect the size of three standard AgNPs samples (30 nm、50 nm and 80 nm), and the results were in accordance with the TEM result provided by manufacturers, which indicated that the established SP-ICP-MS method could detect the size of AgNPs. So the SP-ICP-MS method was used for the characterization of size distribution of the AgNPs in nano-antibacterial consumer products. This proposed method is fast, simple and high sensitivity, which could provide an accurate AgNPs size distribution in nano-antibacterial consumer products.
