    摘要： A column for removal of a component from a fluid is disclosed. The column has a compartment with a cross sectional area. The compartment contains beads having a diameter. A ligand selected to bind to the component is coupled to the beads. The cross-sectional area and bead diameter are selected to maintain a flow velocity of the fluid within the compartment below a first threshold, thereby reducing leaching of the ligand into the fluid. Also described herein is an adsorbent comprising a ligand that is attached to a substrate by an amine bond, wherein the ligand is resistant to dissociation from the substrate.

    摘要： Methods and systems for recovering high-value target ions such as lithium ions from a brine solution, wherein a target-ion-selective adsorbent material (such as bound or unbound adsorbent particles) are mixed with the brine solution to form a slurry, and the slurry is contacted with a filter to capture target-ion-enriched material, which target-ion-enriched material is then contacted with a stripping solution to separate the target ions from the target-ion-enriched material.

    摘要： Methods and systems directed to the separation of tritium from an aqueous stream are described. The separation method is a multi-stage method that includes a first stage during which tritium of a tritium-contaminated aqueous stream is adsorbed onto a separation phase, a second stage during which the adsorbed tritium is exchanged with hydrogen in a gaseous stream to provide a gaseous stream with a high tritium concentration, and a third stage during which the tritium of the gaseous stream is separated from the gaseous stream as a gaseous tritium product.

    摘要： A method for preparing high-purity cannabidiol is characterized in that: the leaves of cannabis and top portions of the plant which account for about one-fifth of the whole plant are used as extraction sites; a technology of combined macroporous adsorption resin chromatography and polyamide chromatography is used for purification; and a mixed solvent system is used for crystallization purification so as to ensure that the yield is improved to the maximum extent under the premise of obtaining a high-purity product. The product obtained from this method contains high-purity CBD; the method has a high yield and is a simple process, and thus easy to industrialize.
