| 摘 要： | 在对各种Ｍ－ＰＡＮ络合物的荧光作出研究之后，发现Ｃｒ（Ⅲ）－ＰＡＮ不产生荧光，但是，在纯乙醇中，由Ａｌ（Ⅲ）－ＰＡＮ络合物的荧光熄灭，可以测定Ｃｒ（Ⅲ）的含量，检出限达１０－８Ｍ。

| Abstract: | After a general investigation of the fluorescence of various metalPAN complexes,it was found that the chromium()PAN did not fluoresce,but that chromium() could be determined in the 10-8 to 10-6 Mrange by the fluorescence quenching of eduminum()PAN complex in absolute ethanol. |
