Abstract

Sorbed Cs on vermiculitized biotite in saturation amount was desorbed by extractions with 1 M K⁺ and Mg²⁺ at varied temperatures. At room temperature, Cs⁺ was readily desorbed by leaching with K⁺ (ca. 100%) but not by Mg²⁺ (ca. 50%). However, the contrary was true for desorption at high temperatures, in which Mg²⁺ desorbed far more Cs⁺ (ca. 100%) than K⁺ (ca. 25%). XRD analysis of Cs-depleted samples suggested that the contrary abilities of K⁺ and Mg²⁺ for Cs desorption at low and high temperatures were attributed to their induced interlayer collapse or expansion during extraction.
