Selection and Testing of "Getters" for Adsorption of Iodine-129 and Technetium-99: A Review

XPS and XAS studies of copper(II) sorbed onto a synthetic pyrite surface

“…The formation of oxidation products such as metallic oxides onto studied surfaces modifies surface reactivity even with iodine tracers and could explain the dispersion of the results (Kd from ∼10 to 700 mL g −1 ) in the literature [15] and the difference observed between the present results and the literature data.…”

Pertechnetate immobilization with amorphous iron sulfide

“…Various remediation methods for technetium contamination in the vadose zone from tank leakage at the Hanford Site have been considered [9][10][11][12][13][14]. The gas-phase approach using hydrogen *Author for correspondence (E-mail: JurissonS@missouri.edu).…”

The function of Sn(II)-apatite as a Tc immobilizing agent

“…Several candidate materials for the uptake and immobilization of TcO4from aqueous solutions have been previously studied, including minerals, organic compounds, inorganic compounds and redox active materials, with varying levels of success. [10][11][12][13] However, many of these studies were performed in deionized water (DIW), or in solutions with simple compositions. A successful candidate material for Tc immobilization through a redox process needs to have two ideal characteristics: high removal capacity/selectivity for TcO4and sufficient reductive potential to convert it to Tc(IV).…”
