Extraction vitamins of group b water-soluble polymers

General lows of extraction of B vitamins in aquatic environments of the solution of polymers (poly-N-vinylpyrrolidone, poly-N-vinilkaprolaktam) has been studied. The influence of polymer concentration and structure on the distribution coefficients and degree of extraction of vitamins has been established. As a result, the direct search of a stable two-phase systems based on water-soluble polymers has been developed effective systems for the extraction of vitamin B from aqueous salt solutions.
