紫外吸收光谱法检验透明胶带的研究

Detection of Scotch Tape by UV-Vis Spectrometry

作为包扎和捆绑物品使用的透明胶带,是爆炸、凶杀、抢劫、盗窃等案件中的重要常见物证之一。文中建立了紫外光谱法检验透明胶带的测定方法,并对收集到的22种透明胶带进行了检验。该方法检材用量少,结果准确性高,方法简便、快速,为法庭科学领域透明胶带的区分检验提供了一种有效方法。

Scotch tape generally used for bounding materials is one of important evidence on some criminal cases, such as explosions, murder, robbery, theft, etc. The detection method of scotch tapes using UV-Vis method is established in this paper. 22 bands of transparent tape are collected and measured with UV-2450. Results show that this method is an effective method for transparent tape detection in forensic science, with less material consumption, high accuracy, and rapid response.
