以国产微晶纤维素膜作固体基质五种多环芳烃的室温磷光法研究

本文考察了10种国产纤维素膜用于多环芳烃固体基质室温磷光(SS-RTP)的可行性。实验表明:MN-C和MN-P两种型号的微晶纤维素膜用于多环芳烃的SS-RTP是适宜的。阴离子交换纤维素膜、CM-纤维素膜和聚酰胺-6膜也能诱导出多环芳烃的RTP来,但其性能逊于前两种。故本文应用MN-C和MN-P两种微晶纤维素膜基质考察了五种多环芳烃的RTP特征,并建立了它们的SS-RTP新方法。并与用滤纸作基质的实验结果进行了比较,表明两种新的固体基质的RTP性能优于滤纸基质。

Study on Room Temperature Phosphorescence of Five Polycyclic Aromatic Hydrocarbons with China-Made Cellulose Microcrystal Membrane as Solid Substrates

The feasibility of using ten kinds of China-made cellulose microcrystal membrane in solid substrate room temperature phosphorescence (SS-RTP) of polycyclic aromatic hydrocarbons (PAHs) has been investigated. The experiments indicate that type MN-C and MN-P cellulose microcrystal membranes are suitable as substrate. With DEAE membrane, CM-cellulose membrane and polyamide-6 thin membrane the RTP of PAHs could be induced too, but these membrane characteristics are poorer than MN-C and MN-P membranes. The other membranes are not suitable as substrate for SS-RTP of PAHs. Therefore RTP characteristics of five PAHs were investigated and new SS-RTP of five PAHs were established with MN-C and MN-P membranes as substrate. The substrates are better than filter paper in analytical characteristics.
