The chemiluminescence of luminol induced by bleaches: a study of glows over periods of time

Jan Gradon, Poland 16-18

In my project I decided to investigate the problems and limitations concerning luminol, one of the most popular chemicals used to detect latent blood. Interestingly, in nearly every household, there are products that can react with luminol and produce a similar chemical response to blood. This often misleads and confuses crime investigators and makes their work much harder. One of these compounds is sodium hypochlorite, which is present in every bleach on the market. In this study, I investigated how bleaches react with luminol and to what extent they can be mistaken for blood traces.
