“…In a recent study two techniques which are based on better understanding of the physiological processes which take place on the skin, have been devised and tested for the enhancement of the sensitivity of this process: exposure to water vapors and accelerated sweating [28].…”

“…However, if traces of iron left on the palm of a suspect could be detected, a connection between the perpetrator and the tool could be revealed. In practice, a ferrous reagent is often sprayed on the skin surface to reveal iron impressions left by an iron tool [2, 3], and this method has been successfully applied in numerous police investigations.…”

When iron-based tools, such as knives or guns, are held, traces of iron can transfer to the skin. However, no previous studies have been published regarding the effect of the elapsed contact time on the transfer of iron species with different valences to the palm. Compared with 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine (PDT), 2,4,6-tri(2′-pyri dyl)-1,3,5-triazine (TPTZ) was found to exhibit a higher sensitivity to iron(II) spectrophotometrically. This work employed 2,4,6-tri(2′-pyridyl)-1,3,5-triazine (TPTZ) and UV spectrophotometry to determine the amounts of iron(II), iron(III), and total iron transferred to human palms from iron tools. It was found that the palmar moisture level was
