Abstract
The improved organic polymeric adsorbent is used to adsorb and remove suspended impurities present in trace amounts in the water being treated in an apparatus for producing ultrapure water for use in the semiconductor industry or in a condensate purifier in steam power generating facilities and it is composed of a particulate or powdered cation exchange resin and/or anion exchange resin. The improvement is that this adsorbent has such a surface layer structure and morphology that granules are seen to bind with one another when examined under a scanning electron microscope in a field of view ranging from a magnification of 50 to 200,000. The adsorbent may be used as the constituent of a packing layer and/or a filter layer to make a material for removing suspended impurities.
