摘　　要：本文根据邻菲(口罗)啉在弱酸条件下与Fe^(2+)反应生成稳定的桔红色给合物的原理,对遗留在各种纸张、本色木、地板砖.地板革等承受客体上的灰尘鞋印进行显现,获得较佳效果.对微弱或潜在灰尘鞋印,用上述方法处理后,再用荧光粉末刷涂,用多波段光源显现效果更佳.Normally, there is Fe2+ in soils and dust. Reaction of 10 - phenanthroline with Fe2+ under weak acid condition can produce tangerine products. With this principle we have developed dust shoeprints on paper, wood, floor brick. For very weak or latent dust shoeprints, after treated with 10 - phenanthroline, we brush fluorescent powder and then use 535nm, 580nm light source, the results are quite better.
