Let's make recycling blue

Targeted audience: 14-19 years old students.

A versatile system for a sustainable recovery of Critical Raw Materials from water

Nowadays Prussian Blue can be used to capture critical raw materials in order to recycle them. As a matter of fact, these materials are really rare and expensive. Its particular structure can interact with CRMs isotopes and capture them. Actually, it is also used in the pharmaceutical sector to soak up dangerous substances in infected hosts. (download pdf).

Separation of copper and iron - two approaches

Precipitation and leaching: A more or less complex mixture of metal salts can be separated in the pure metals using a sequence of reactions causing some components to precipitate. This strategy is utilized in gold mining operations where gold is leached using cyanides. (download pdf).
