Sodium polystyrene sulfonate, PSS for short, is a very important polymer. Sodium polystyrene sulfonate also plays an important role in fuel cells, biomedicine, and chromatographic calibration. This article will briefly introduce the application of polystyrene sodium sulfonate (PSS).
Sodium polystyrene sulfonate (PSS) is used to prepare adsorption ultrafiltration membranes and is used to control heavy metal water pollution. Sodium polystyrene sulfonate (PSS) has strong hydrophilic properties. When it gels in water, it will migrate to the surface of particles and then be mainly fixed on the surface of particles or the surface of pore channels. The adsorption ultrafiltration membrane prepared based on it not only has the ability to remove Substances such as macromolecules and colloids can also remove various toxic and harmful cations in water at the same time.
Polystyrene sodium sulfonate (PSS) is also considered an ideal choice for forward osmosis draw fluid due to its advantages as an ionic polymer. On the one hand, sodium polystyrene sulfonate (PSS) can be ionized to generate a larger osmotic pressure, thereby producing a higher water flux; on the other hand, the reverse salt flux is low.
Sodium polystyrene sulfonate (PSS) is used to prepare metal organic framework films and is used in the field of ion separation. Patent CN105854647B [1] describes that polystyrene sodium sulfonate (PSS) and metal hydroxide nanowire solution are mixed and stirred, electrostatic adsorption and recombination are performed, and then polystyrene sodium sulfonate (PSS) is introduced into the metal organic framework in situ. In the pores of the material film, the sulfonate radicals can be used to modify the inner wall of the pores of the metal-organic framework film, changing its affinity for ions and enabling it to have the function of ion separation.
Polystyrene sulfonate sodium (PSS) can also be used to prepare polystyrene sulfonate sodium cation exchange resin, which is used in the auxiliary treatment of hyperkalemia.
To summarize, polystyrene sulfonate (PSS), as an indispensable member of polyelectrolytes, is often used as a conductive and antistatic resin for electrical recording and electrophotography substrates. It is also a common reactive resin. Emulsifier, water treatment agent.
