Compositions are provided for efficient uranium extraction, for example from wastewater, seawater, or other water sources. The compositions can include a functionalized porous organic polymer functionalized with one or more uranium binding moieties, e.g. having a plurality of amidoxime or amidrazone groups covalently attached thereto. The compositions can include covalent organic frameworks, porous aromatic frameworks, and various porous organic polymers, especially those having a hierarchical pore size distribution over a range of pore sizes. The compositions can have functional groups such as amidoxime or an amidrazone covalently attached thereto. The hierarchical pore size distribution can be determined based upon at least 60% of the pore sizes in the range of pore sizes having a pore volume of at least 0.01 cm.sup.3 g.sup.−1 in the pore size distribution at 77 K. Methods of making the compositions and methods of using the compositions are also provided.

A core-shell type amine-based carbon dioxide adsorbent is described, including a chelating agent resistant to oxygen and sulfur dioxide, to inhibit oxidative decomposition of amine. As a core, a porous support is employed on which an amine compound is immobilized, and, as a shell, an amine layer resistant to inactivity by sulfur dioxide is utilized. Such adsorbent exhibits high oxidation resistance because the chelating agent functions to remove a variety of transition metal impurities catalytically acting on amine oxidation. In addition, the sulfur dioxide-resistant amine layer of the shell selectively adsorbs sulfur dioxide to protect the amine compound of the core and, at the same time, the amine compound of the core selectively adsorbs only carbon dioxide. Sulfur dioxide adsorbed on the shell is readily desorbable therefrom at about 110° C. and thus remarkably improved regeneration stability is obtained during temperature-swing adsorption (TSA) processes in which sulfur dioxide is present.

A functional material is provided and includes a porous carbon material derived from a plant-derived material as a raw material, wherein a bulk density of the porous carbon material is in a range of 0.2 grams/cm.sup.3 to 0.4 grams/cm.sup.3, a value of a cumulative pore volume in a range of 0.05 μm to 5 μm in pore size of the porous carbon material based on a mercury press-in method is in a range of 0.4 cm.sup.3 per 1 gram of the porous carbon material to 1.2 cm.sup.3 per 1 gram of the porous carbon material, and a value of a pore volume of the porous carbon material based on an MP method is in a range of 0.04 cm.sup.3 per 1 cm.sup.3 of the porous carbon material to 0.09 cm.sup.3 per 1 cm.sup.3 of the porous carbon material.
