A method for sequestering technetium is disclosed. The method includes contacting technetium with apatite under reducing conditions whereby the technetium is absorbed by the apatite.

Apatite sequestration of technetium

Approaches for alkali metal extraction, sequestration and recovery are described. For example, a method of recovering alkali metals includes providing a CST or CST-like (e.g., small pore zeolite) material. The alkali metal species is scavenged from the liquid mixture by the CST or CST-like material. The alkali metal species is extracted from the CST or CST-like material.
