Organic-pollution-resistant ion exchange resin and preparation method and application thereof
Implementations herein relate to a method for preparing organic-pollution-resistant ion exchange resins and application thereof. The method includes adding modified inorganic particles to prepare novel ion exchange resins containing inorganic particles modified by a parcel modifier. A weight ratio between the monomer of the ion exchange resins and the modified inorganic particles is about 0.1% to 30%. The method may increase moisture content of the resins 3 to 30% such as to improve the structures of the resins, and therefore increase the regeneration efficiency 0.4 to 70%, as compared to conventions resins. The method improves resistance of resins to organic pollution, increases regeneration efficiency, and extends service life of the resins. In the process of water treatment, the ion exchange resin of the implementations may be regenerated with long-term stability. In addition to securing the water treatment efficiency, the method may avoid frequent replacement operations and lower the costs.

ION EXCHANGE REACTOR WITH PARTICLE TRAPS FOR LITHIUM EXTRACTION
The present invention relates to the extraction of lithium from liquid resources such as natural and synthetic brines, leachate solutions from clays and minerals, and recycled products. For the extraction of lithium from the liquid resources, an ion exchange reactor has a tank, ion exchange particles, particle traps, and provision to modulate pH of the liquid resource.
Composite membranes and applications thereof
In one aspect, a composite membrane comprises a polymeric host comprising polybenzimidazole or polybenzimidazole derivative and graphene oxide dispersed in the polymeric host, the graphene oxide at least partially functionalized with phosphonic acid moieties, phosphonate moieties or combinations thereof. In some embodiments, the functionalized graphene oxide is homogeneously dispersed in the polymeric host and/or is not agglomerated in the polymeric host.

Adsorbent of micotoxins based on a betaine derivative for balanced animal foods
The present invention provides a mycotoxin adsorbent based on a highly specific betaine derivative for trichothecenes A and B, and especially for vomitoxin (or deoxynivalenol) and T-2 toxin; as well as a process for preparing said mycotoxin adsorbent. The mycotoxin adsorbent of the invention is obtained by modifying the surface of an aluminosilicate by means of an organic amphoteric compound with a carboxyl group that provides it with high polarity properties. The mycotoxin adsorbent is useful for preparing balanced feed from animals that avoid the toxic effects of mycotoxins.

SORBENT FOR A DIALYSIS DEVICE AND DIALYSIS SYSTEM
The invention relates to a sorbent for removing metabolic waste products from a dialysis liquid, the sorbent comprising a soluble source of sodium ions. The sorbent comprises an ion exchange system which converts urea to ammonium ions and which is configured to exchange ammonium ions for predominantly hydrogen ions and to exchange Ca, Mg, and K for predominantly sodium ions. The soluble source of sodium ions overcomes an initial drop in sodium concentration in regenerated dialysate. When used in conjunction with an infusion system configured to utilise exchange of Ca, Mg and K for sodium during dialysate regeneration a desired sodium ion concentration can be maintained.
