Catalytic Action of Copper on the Oxidation of Structural Iron in Vermiculitized Biotite
Biotite Catalyst Copper Iron Oxidation Vermiculite
2012/2/7
The ferrous iron content of two vermiculitized biotites decreased by treatment with 0.1 N salts of copper at 70°C from 9.1–14% to 1.8–2.6%. Presumably, interlayer copper ions acted as a catalyst (here...
