A simple and durable luminescent powder can be conveniently prepared by mixing washing powder, luminol, and potassium hexacyanoferrate(III) to carry out impressive chemiluminescence experiments. The students particularly enjoyed using the mixture in a light-colored painting activity. In addition, various washing powders, brought from home by the students, can be tested indirectly for the presence of oxygen-based bleaching agents via their “luminosity”. The luminescent powder offers many starting points for lessons on the topics of reaction energy, light, and oxygen, combined with a playful fun factor, and is suitable as a motivating introduction or as a school experiment.
期刊介绍：
The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
