Oxidative Power of Smectites Measured by Hydroquinone
Oxidative Power Smectites Hydroquinone
2012/2/15
The oxidative power of a smectite can be measured quantitatively by oxidation of hydroquinone to p-benzoquinone in a clay slurry. Oxidation takes place in the presence of O2 (air) but not N2 unless Fe...
