SALGADO, Guillermo et al. Electrogenerated chemiluminescence of luminol using low-cost electrodes. Quím. Nova [online]. 2006, vol.29, n.2, pp.381-384. ISSN 0100-4042.

The purpose of the study was to observe eletrogenerated chemiluminescence (ECL) of luminol using different materials as electrodes such as wires, nails, coins, razor blades, etc. Based on the experimental observations and the mechanisms proposed in the literature, students should be capable of analyzing their results in order to understand the phenomena studied. Students could then elaborate a mechanism of action consistent with the experimental results which could rationalize the formation of intermediates in the reaction and the dependence of ECL on solution pH in addition to other points of interest

Palabras clave : chemiluminiscence; chemical education; demonstrations experiments.
