Characterization of the Solids Obtained by Pillaring of Griffithite (High Iron Content Saponite) with Al-Oligomers
Al13-Keggin Polycation Griffithite Iron-Saponite Pillaring Porosity Saponite
2011/12/22
Abstract: Griffithite, a high Fe content saponite (Griffith Park, California) was pillared with Al polymeric solutions, using different Al/clay ratios. The cation exchange began when Al-polycation sol...
The Al Pillaring of Clays. Part II. Pillaring with [Al13O4(OH)24(H2O)12]7+
Aluminium Hectorite Keggin ion Pillaring Saponite
2011/12/29
Hectorite and saponite are exchanged with [Al13O4(OH)24(H2O)12]7+ and the amount of Al3+ adsorbed and Na+ released are followed as a function of the exchange conditions. On saponite the reaction is a ...
The Al Pillaring of Clays. Part I. Pillaring with Dilute and Concentrated Al Solutions
Aluminium Hectorite Laponite Pillaring Saponite
2011/12/30
Saponite, hectorite, and laponite have been pillared with cationic Al clusters, and special attention has been given to the solution chemistry or Al. Pillared saponite is obtained after exchange with ...
Pillaring Processes of Smectites with and without Tetrahedral Substitution
Beidellite Hydroxy-aluminum complex Nuclear magnetic resonance Pillared interlayered complex Smectite Tetrahedral substitution
2012/1/10
Pillaring of montmorillonite and beidellite with aluminum polyhydroxypolymer takes place first by the saturation of the cation-exchange capacity by monomeric and/or dimeric aluminum hydroxide species ...
