Chelating organic acids hampered the hydrolytic reactions of Al and affected the nature of the crystalline aluminum hydroxides. Chemical composition, structure, size, nature of functional groups, and ...
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...
