Spherical macroporous adsorbents with active sites capable of hydrogen bonding adsorption based on urea-formaldehyde condensed polymer were synthesized via reversed suspension polymerization. The properties of the obtained adsorbent were also investigated in detail. The results showed that the water permeability could be improved by adding hydroxyl-containing organic compound moiety into the adsorbent. The specific surface area and average pore diameter of these adsorbents increased while the porosity first increased then decreased with the increase of the amount of the added hydroxyl-containing compound.
