COMPLEMENTARY REFINING WITH PULVERULENT MIXTURES OF POLAR RESINOUS ADSORBENTS, ACTIVATED CARBON, AND INORGANIC ADSORBENTS

Properly selected combinations of finely divided adsorbents consisting of polar resinous adsorbents, activated carbon, and/or inorganic adsorbents complement each other in purifying substrates such as sugar solutions, water, and organic liquids by the removal of color, color precursors, and haze. This mutual enhancement of the refining powers of the individual adsorbents yields a purification much greater than would be expected from considering the refining capacities of the separate adsorbents alone. Micronized ion exchange resins constitute an important class of polar resinous adsorbents. © 1969, American Chemical Society. All rights reserved.
