A metal adsorption agent including a chelating agent (A) and a chelating agent (B), wherein the chelating agent (A) is a metal adsorption agent containing a carrier having a glucamine-type functional group, and the chelating agent (B) is a metal adsorption agent containing a carrier having a thiol group, a thiourea group, an amino group, a triazabicyclodecene-inducing group, a thiouronium group, an imidazole group, a sulfonate group, a hydroxy group, an aminoacetate group, an amidoxime group, an aminophosphate group, or any combination of these groups. The carrier of each of the chelating agent (A) and the chelating agent (B) may be silica, a silica component-containing substance, polystyrene, or crosslinked porous polystyrene. The solution may contain water or an organic solvent.

A method of fabricating an oleophilic foam includes providing a foam comprising a base material. The base material is coated with an inorganic material using at least one of an atomic layer deposition (ALD), a molecular layer deposition (MLD) or sequential infiltration synthesis (SIS) process. The SIS process includes at least one cycle of exposing the foam to a first metal precursor for a first predetermined time and a first partial pressure. The first metal precursor infiltrates at least a portion of the base material and binds with the base material. The foam is exposed to a second co-reactant precursor for a second predetermined time and a second partial pressure. The second co-reactant precursor reacts with the first metal precursor, thereby forming the inorganic material on the base material. The inorganic material infiltrating at least the portion of the base material. The inorganic material is functionalized with an oleophilic material.

A composite extractant-enhanced polymer resin comprising an extractant and a polymer resin for direct extraction of valuable metals such as rare earth metals, and more specifically, scandium, from an acid-leaching slurry and/or acid-leaching solution in which ferric ions are not required to be reduced into ferrous ions. The extractant may be cationic, non-ionic, or anionic. More specifically, the extractant di(2-ethylhexyl)phosphoric acid may be used. The polymer resin may be non-functional or have functional groups of sulfonic acid, carboxylic acid, iminodiacetic acid, phosphoric acid, or amines. The composite extractant-enhanced polymer resin may be used for extraction of rare earth metals from acid-leaching slurries or solutions.

An apparatus for encapsulating a material includes a first channel in fluid communication with a source of a material for encapsulation, at least one second channel in fluid communication with a source of a photopolymerizable compound, and at least one third channel in fluid communication with a source of an encapsulating fluid. Flow of the photopolymerizable compound into the first channel produces sheath flow in the first channel such that the material is within the polymerizable compound. Addition of the encapsulating fluid produces encapsulation precursors. Upon irradiation via a UV-radiation source, the photopolymerizable compound in the encapsulation precursor forms a polymer shell encapsulating the material for encapsulation. Materials such as nanoparticle organic hybrid materials (NOHMs) and a metal-organic frameworks (MOFs) can be thus encapsulated as carbon sequestration micro particles, as the polymer shell is permeable by gases such as carbon dioxide but selectively rejects other compounds such as water.
