Abstract
The interaction of natural biotites with dilute nickel sulfate solutions at various pHs are studied by X-ray powder diffraction, thermogravimetric analysis, and chemical analysis. K ⇆ Ni, Mg ⇆ Ni, and to a lesser extent Fe ⇆ Ni ion exchange is shown to occur. Nickel can both enter octahedral layers and act as an interlayer cation. Tetrahedral layers have a virtually invariable composition. The mechanoactivation of biotites enhances exchange reactions.
