  2. Polystyrene sulfonate - Wikipedia

    en.wikipedia.org/wiki/Polystyrene_sulfonate

    Polystyrene sulfonates release sodium or calcium ions in the stomach in exchange for hydrogen ions. When the resin reaches the large intestine the hydrogen ions are exchanged for free potassium ions, and the resin is then eliminated in the feces.

  3. 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.

  4. 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).

  5. 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.

  6. Polystyrene (drug delivery) - Wikipedia

    en.wikipedia.org/wiki/Polystyrene_(drug_delivery)

    These methods include polystyrene microspheres, nanoparticles, and solid foams. In the biomedical engineering field, these methods assist researchers in drug delivery, diagnostics, and imaging strategies. [1] [2] A common group of medication that utilizes a combination of polystyrene and sulfonate functional groups are polystyrene sulfonates. [3]

  7. Colestilan - Wikipedia

    en.wikipedia.org/wiki/Colestilan

    Colestilan (INN, trade name BindRen) is a medication that acts as a phosphate binder [1] and bile acid sequestrant. [2] It is an ion-exchange resin, is an orally administered bile acid sequestrant that is being developed by Mitsubishi Tanabe Pharma Corporation for the treatment of hypercholesterolaemia and hyperphosphataemia.

  8. Polymer adsorption - Wikipedia

    en.wikipedia.org/wiki/Polymer_adsorption

    For example, polystyrene sulfonate has monomers containing negatively charged side chains which can adsorb positively charged adsorbates. Polystyrene sulfonate will ...

  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.
