Details
Polyvinylpyrrolidone (PVP K88-96) is a dispersant with an average molecular weight of 1300000. It has excellent solubility, biocompatibility, physiological inertness, film-forming ability, membrane protection capability, and the ability to complex with various organic and inorganic compounds. It is stable to acids, salts, and heat, and therefore has a wide range of applications.
It is used to absorb phenols and tannic acids from aqueous extracts to purify plant enzymes. It is also used as a chromatography adsorbent to separate aromatic acids, aldehydes, and phenols.
