Facile construction of [email protected] zeolite imidazolate Framework-67 to selectively remove uranyl ions from aqueous solution

Add time:07/22/2019    Source:sciencedirect.com

The novel [email protected] was utilized as a promising adsorbent for the adsorption and separation of U(VI) ions from aqueous solutions for the first time. The material performed potential adsorption capacity of 292.2 mg g−1 and an outstanding selectivity on U(VI) at pH = 4.5. Furthermore, the adsorption performance of this new adsorbent agreed well with the Langmuir, Freundlich isotherm and pseudo-first-order kinetic model. Given the advantages of this adsorbent such as high adsorption capacity, selectivity, and environment-friendly, it may be an outstanding candidate for the adsorption of U(VI) ions for practical application.
