The system includes a liquid inlet arranged to accept a liquid into the system; an acid-based cation-exchange resin in fluid communication with the liquid inlet, the resin adapted to exchange cations in the accepted liquid with H+ ions on the resin; an ozone dissolving apparatus in fluid communication with the liquid inlet and the acid-based cation-exchange resin; and a liquid outlet in fluid communication with the liquid inlet, the acid-based cation-exchange resin and the ozone dissolving apparatus. The ozone dissolving apparatus and the acid-based cation-exchange resin cooperating to produce the acidic ionized ozonated liquid for dispensation out of the system via the liquid outlet.

The invention relates to a method of separating and recovering xylose from a xylose-containing plant-based solution. The method is performed in a chromatographic separation system, which comprises one or more weak base anion exchange resins and optionally one or more other resins selected from strong acid cation exchange resins and weak acid cation exchange resins, by passing the solution through the separation system, followed by recovering at least one fraction enriched in xylose. Optionally, a rhamnose fraction may also be recovered.

A method for preparing lithium concentrate from natural lithium-bearing brines was developed. The brine is first subjected to purification from the suspended solids, then filtered through a static layer of a granulated sorbent based on LiCl.2Al(OH).sub.3.mH.sub.2O, where m=3-5, to obtain a primary lithium concentrate. The process is carried out in sorption-desorption units consisting of 4 columns, two of which are in the process of sorption of lithium chloride from the brine, one column is in the process of washing the sorbent saturated with lithium chloride from the brine, and one column is in the process of lithium chloride desorption. The primary lithium concentrate is converted to a secondary lithium concentrate by concentration in evaporative pools or reverse osmotic concentration-desalination. The secondary lithium concentrate is used for further production of lithium chloride or lithium carbonate.
