摘要
通过对多种无机化合物筛选,选出可以适用于手印显现的小颗粒试剂。用不同浓度的表面活性剂对其进行改性,配置出新型小颗粒试剂,并对其稳定性进行研究。多种小颗粒试剂可以对不同客体、不同遗留时间、潮湿客体上的手印进行显现。碳酸钡、氧化铜、氢氧化铜3种小颗粒试剂对手印显现具有较好的显现效果,可以应用于手印显现。
Selecting the inorganic compounds can be applied to the appearance of fingerprint by screening a variety of inorganic compounds. The optimum concentration was found, modified with different concentrations of surfactants, and a new type of small particle reagent was deployed to study its stability. A variety of small particle reagents could show the fingerprint on different objects, different remaining time and wet objects. Three new small particle reagents (BaC03, CuO, and Cu(OH)2) are placed for a period of time, and they have a good effect after being stirred or shaken.
