A process for reducing or removing at least 90% of sulfur in a tall oil composition, e.g., to a level of 15 ppm or less is disclosed. The process employs at least a first desulfurization and a second desulfurization treatment in parallel or in series. The first treatment comprises adsorptive desulfurization, wherein the adsorbent material comprises silica adsorbent having an average pore size between 50-200 Å, BET surface area of at least 300 m.sup.2/g, pore volume of 1.20 to 3.00 cc/g, and a silanol [Si—OH] level of 0.5 to 5 unit/nm.sup.2. The second desulfurization treatment is selected from adsorptive treatment, heat treatment, distillation, extraction, oxidation, reduction, hydrogenation, and sulfur scavenging for a reduced sulfur content.

The present technology relates to a method for improved recovery of phosphorylated compounds (e.g., phosphorylated glycans). In particular, the present technology utilizes certain chelator additives in a solution to wash and elute the phosphorylated compounds from a solid phase extraction cartridge.

A method for recovering lithium is provided. The method includes the following steps. A lithium-containing solution is provided. A manganese oxide adsorbent is immersed in the lithium-containing solution, and a reducing agent is added to carry out an adsorption reaction, and the manganese oxide adsorbent is immersed in a solution containing an oxidizing agent to carry out a desorption reaction.

A device and a method for stabilizing wine or other vegetable beverages by removal, in whole or in part, of agents responsible for instability, including proteins and metals, are provided. The device has a tubular container filled internally at least partly with particles of support material covered with a layer of a mesoporous nanostructured adsorbent material comprising titanium oxide, adapted to absorb proteins and metals.

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.

The present invention provides systems and methods for concentrating and recovering phosphate from samples. The method comprises using immobilized PBP for binding phosphate and a desorption solution having a pH of 11 or greater to recover phosphate from a sample when the phosphate is found at very low detection levels. Further systems and method for removing arsenate for water sources is also provided.

The present disclosure relates to charge-bearing polymeric materials and methods of their use for purifying fluid samples from micropollutants, such as anionic micropollutants.
