Adsorption of Thorium Ions Using Trioctylphosphine Oxide Impregnated Dowex 1×4 Powder

Аннотация

Dowex 1×4-trioctylphosphine oxide powder (DTP) was prepared, characterized, and studied as an adsorbent for the adsorption of Th(IV) from aqueous solutions. The adsorption of Th(IV) strongly depends on pH. The adsorption follows the pseudo-second-order kinetics, and the adsorption isotherms agree well with the Langmuir model with a maximum adsorption capacity of 132.1 mg g⁻¹.
