Reaction of OH-Al Polymers with Smectites and Vermiculites
Smectite Vermiculite OH-Al Pillared clay
2011/12/30
Five montmorillonites, one hectorite, and two vermiculites were treated with OH-Al solutions containing rapid- and slow-reacting polymers of similar concentrations. With all smectites, both rapid- and...
Reduction of the Cation-Exchange Capacity of Montmorillonite by Take-Up of Hydroxy-Al Polymers
Cation-exchange capacity Hydroxy-Al polymer Interlayer Montmorillonite Smectite
2012/1/12
The cation-exchange capacity (CEC) of Na-Al- and Ca-Al-montmorillonite after neutralization with NaOH or Ca(OH)2 was studied at three Al levels: 10, 25, and 50% of the CEC. Hydroxy-Al polymers were ef...
