  2. Polystyrene sulfonate - Wikipedia

    en.wikipedia.org/wiki/Polystyrene_sulfonate

    Sodium polystyrene sulfonate is used as a superplastifier in cement, as a dye improving agent for cotton, and as proton exchange membranes in fuel cell applications. In its acid form, the resin is used as a solid acid catalyst in organic synthesis , [ 16 ] mostly commonly under the tradename Amberlyst.

  3. Potassium binder - Wikipedia

    en.wikipedia.org/wiki/Potassium_binder

    Potassium binders are medications that bind potassium ions in the gastrointestinal tract, thereby preventing its intestinal absorption. This category formerly consisted solely of polystyrene sulfonate, a polyanionic resin attached to a cation, administered either orally or by retention enema to patients who are at risk of developing hyperkalaemia (abnormal high serum potassium levels).

  4. Counterion - Wikipedia

    en.wikipedia.org/wiki/Counterion

    Polystyrene sulfonate, a cation-exchange resin, is typically supplied with Na + as the counterion. In chemistry , a counterion (sometimes written as " counter ion ", pronounced as such) is the ion that accompanies an ionic species in order to maintain electric neutrality.

  5. Sodium zirconium cyclosilicate - Wikipedia

    en.wikipedia.org/wiki/Sodium_zirconium_cyclosilicate

    Cross-sections of ZS-9 pores with three different ions (K⁺ = potassium, Na⁺ = sodium, Ca²⁺ = calcium). The specificity for potassium is thought to be caused by the diameter and composition of the pores, which resembles potassium channels. ZS-9 is a zirconium silicate. Zirconium silicates have been extensively used in medical and dental ...

  6. Patiromer - Wikipedia

    en.wikipedia.org/wiki/Patiromer

    Patiromer works by binding free potassium ions in the gastrointestinal tract and releasing calcium ions for exchange, thus lowering the amount of potassium available for absorption into the bloodstream and increasing the amount that is excreted via the feces. The net effect is a reduction of potassium levels in the blood serum. [4] [11]

  7. Ion-exchange resin - Wikipedia

    en.wikipedia.org/wiki/Ion-exchange_resin

    Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.

  8. Lignosulfonates - Wikipedia

    en.wikipedia.org/wiki/Lignosulfonates

    Lignosulfonates (LS) are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. [1] Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. [2]

  9. PEDOT:PSS - Wikipedia

    en.wikipedia.org/wiki/PEDOT:PSS

    Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is a composite material where PEDOT (the conductive polymer) provides electrical conductivity, and PSS (polystyrene sulfonate) acts as a counter-ion to balance the charge and improve the water solubility and processability of PEDOT.
