Polymeric adsorbents are very porous spherical polymers based on highly crosslinked, macroreticular polystyrene, aliphatic, or phenol-formaldehyde condensate polymers. Polystyrenic adsorbents are more selective to non-polar products and their pore size has been tightly controlled to enhance this selectivity.The variations in surface area and pore volume give each product unique advantages in certain applications. Polyacrylic adsorbents are designed to remove hydrophilic organic compounds from less polar solutions / solvents。
