Gold can be Precipitated With Vitamin C

Chemist Eva-Maria Felix uses vitamin C to precipitate gold. Eva is a doctoral student in the research group of Professor Wolfgang Ensinger in the Department of Material Analysis is working on making nanotubes of gold. The technique involves precipitating gold from an aqueous solution onto a pretreated film with many tiny channels. The metal on the walls of the channels adopts the shape of nanotubes; after which the film is dissolved. Toxic chemicals ...
