Translated title of the contributionEvery school has electronic scrap - a model experiment to recycle gold from computers
Those who want to work with gold nanoparticles are often hindered by the fact that schools do not have enough money to buy chemicals that contain gold.
This article presents a model experiment, which is very relevant for context-oriented teaching, namely, the processing of electronic scrap that contains gold. This scrap is often disposed of with normal waste, even in schools. In addition, this article presents critical thinking approaches to improper recycling in parts of the so-called Third World, encourages an awareness of the high material value of this scrap —which is unknowingly wasted— and, last but not least, presents the production of gold acid, which can be used for the synthesis of the gold nanoparticles mentioned above.
