ABSTRACT:
A method for removing water-soluble macromolecular compounds is characterized by addition of alkali polyphosphates to an aqueous solution containing residual amounts of cationic, anionic, or amphoteric water-soluble macromolecular compounds, formation of insoluble complexes of the alkali polyphosphate and the water-soluble macromolecular complexes, and separation of the resulting complexes from the aqueous solution. This method does not affect the quality or yield of other important components in the aqueous solution.
