What is the application of Poly(styrene sulfonic acid)?

Aug 18，2021

Sodium polystyrene sulfonate (PSS ,Poly(styrene sulfonic acid) sodium salt) is an organic compound, light amber liquid, odorless, and easily soluble in water. Sodium polystyrene sulfonate solution is a water-soluble polymer with a unique effect, used in reactive emulsifiers, water-soluble polymers (coagulants, dispersants, container cleaning agents, cosmetics, etc.), water treatment agents (dispersion Chemicals, flocculants), sulfur exchange resins (membrane), photographic agents (membrane), semiconductors, imaging films, heat conduction products, etc.

Application

Poly(styrene sulfonic acid (PSS) is used to prepare adsorption ultrafiltration membranes and is used to treat heavy metal water pollution. Sodium polystyrene sulfonate (PSS) has strong hydrophilic properties. When gelling in water, it will migrate to the surface of the particles and then be mainly fixed on the surface of the particles or the surface of the pore channels. The adsorption ultrafiltration membrane prepared based on it not only can remove water Macromolecules, colloids and other substances, and can simultaneously remove various toxic and harmful cations in the water.

Poly(styrene sulfonic acid (PSS) is also considered an ideal choice for forward osmosis draw fluid, thanks to its advantages as an ionic polymer. On the one hand, sodium polystyrene sulfonate (PSS) can ionize to produce a larger osmotic pressure, thereby generating a higher water flux; on the other hand, the reverse salt flux is lower.

Poly(styrene sulfonic acid (PSS) is used to prepare metal-organic framework films, which are used in the field of ion separation. Patent CN105854647B describes that polystyrene sulfonate (PSS) and metal hydroxide nanowire solution are mixed and stirred, electrostatically adsorbed and compounded, and then polystyrene sulfonate (PSS) is introduced into the pores of the metal organic framework film in situ Inside, the sulfonate group can modify the inner wall of the pores of the metal organic framework film, change its affinity for ions, and make it have the function of ion separation.

Poly(styrene sulfonic acid (PSS) can also be used to prepare sodium polystyrene sulfonate cation exchange resin, which is used in the adjuvant treatment of hyperkalemia
