Functionalized polymer adsorbents for removing impurities from a feed stream comprising an active pharmaceutical ingredient (API) include particles of functionalized with at least one functional moiety capable of binding one or more contaminants, the polymer being a macroreticular polymer and the functionalized polymer adsorbents having a pore volume of at least 0.65 cm.sup.3/g. Alternatively, the adsorbent can comprise a polymer functionalized with either 2,4,6,-dimercaptotriazine-ethylenedithiol (DMT-EDT) adduct, 2,4,6,-trimercaptotriazine-ethylenedithiol (TMT-EDT) adduct, or a combination thereof, and the polymer can be either a macroreticular polymer or a swellable polymer. The adsorbents can be used in either continuous or batch processes for removing contaminants from an API-containing feed stream wherein the contaminants can include elemental impurities, particularly palladium.

The present invention provides a cellulose porous gel microsphere with uniform particle size, a preparation method and application. Based on the liquid-liquid dispersion theory and the innovation of the underlying technology, the present invention proposes the preparation of high-performance cellulose porous gel microspheres by cellulose acetate solution with low viscosity. The present invention is environmental-friendly, low in requirements for equipment, low in cost, and easy for expanded production and application. The cellulose acetate with low viscosity is used as the raw material, and the prepared cellulose porous gel microspheres have high sphericity, uniform particle size, moderate microsphere pore size, high mechanical strength and excellent pressure/flow rate performance and are suitable for the modification of various ligands and the separation and the purification of various biomacromolecules in various modes after modification. The present invention can compete with agarose porous gel microspheres and can realize efficient separation of the biomacromolecules in chromatography.
