What is styrene sulfonate?
Sodium styrenesulfonate (NaSS) is a highly reactive vinyl monomer containing a hydrophilic sulfonate group. Significant advantages of NaSS as compared with other monomers are low toxicity and high thermal stability. NaSS is widely used to improve dyeability of acrylic and polyester fibers.
Is polystyrene sulfonate biodegradable?
Poly(styrene sulfonic) acid and its monovalent salts are highly water soluble but the polymers are stable as the backbone structure is vinylic in nature. Hence this material will be biocompatible but may not be easily biodegradable in blood compositions. This material can be used in oral drug delivery system.
What is polystyrene sulfonate used for?
Descriptions. Sodium polystyrene sulfonate is used to treat high levels of potassium in the blood, also called hyperkalemia.
How does polystyrene sulfonate work?
How does it work (mechanism of action)? Sodium polystyrene sulfonate is a cation-exchange resin taken orally that is used to reduce high levels of potassium in the blood (hyperkalemia). Sodium polystyrene sulfonate removes potassium by exchanging sodium ions for potassium ions in the intestine.
Is polystyrene bad for the environment?
Like other plastic, when polystyrene is littered or leaks out of supply chains it can harm wildlife and last for years and years. Made from chemicals that come from oil and gas, styrene is one of the main ingredients and is a suspected health hazard.
Is polystyrene a plastic?
Polystyrene is a type of plastic which is not commonly recycled and should be placed in the waste bin.
What causes hyperkalemia?
Hyperkalemia can happen if your kidneys don’t work properly and cannot remove potassium from your body or if you take certain medicines. Kidney disease is the most common cause of hyperkalemia. Your kidneys help control the balance of potassium in your body.
What is calcium polystyrene sulfonate used for?
Calcium polystyrene sulfonate (CPS) has long been used to treat hyperkalemia in patients with chronic kidney disease (CKD).
What are the negative effects of polystyrene?
Why avoid polystyrene foam? Polystyrene foam contains the chemical styrene, which has been linked to cancer, vision and hearing loss, impaired memory and concentration, and nervous system effects…the list goes on.
Is polystyrene harmful to humans?
In addition, the US National Research Council’s 2011 National Toxicology Program confirmed that styrene, the precursor of polystyrene, was “reasonably anticipated to be a human carcinogen” [6], and therefore a potential occupational health hazard.
Is polystyrene harmful?
Polystyrene foam not only poses a threat to human health, but can also be harmful to the environment. Foam is lightweight and is easily blown by wind or washed away by rain into water sources. It is also very brittle, and can break into small pieces that are easy for animals to eat.
What is sodium polystyrene sulfonate?
Sodium polystyrene sulfonate (SPS, Kayexalate, Kionex) is a cation exchange resin that exchanges sodium for secreted K in the colon.
Why is sodium polystyrene sulfonate used for hyperkalemia?
Sodium polystyrene sulfonate is used to treat high levels of potassium in the blood, also called hyperkalemia. Sodium polystyrene sulfonate works differently from other medicines because it passes into your intestines without being absorbed into your blood stream.
How much water do you mix with sodium polystyrene sulfonate?
If you are taking sodium polystyrene sulfonate powder by mouth, mix the powder with 20 to 100 mL (about 1 to 3 ounces) of water or syrup as directed by your doctor.
Is sodium polystyrene sulfonate safe during pregnancy?
Because sodium polystyrene sulfonate is not absorbed into the bloodstream, this medicine is not expected to be harmful during pregnancy or while nursing a baby. Tell your doctor if you are pregnant or breast-feeding. How is sodium polystyrene sulfonate given?
