    摘要： A method for evaluating performance of a chemical filter element is disclosed. A moisture content, a weight or a pressure loss of a filter element including an ion exchanger is determined, and the determined value is compared with a prescribed value. Alternatively, the determined value is converted into a residual ion exchange capacity of the filter element, and the residual ion exchange capacity is compared with a prescribed value. When the determined value or the residual ion exchange capacity is equal to or less than the prescribed value, the filter element is exchanged. On the other hand, when the determined value or the residual ion exchange capacity is more than the prescribed value, after waiting a prescribed period, the determining step and the comparing step are repeated.

    摘要： A polymer substrate for radiation-induced graft polymerization in the form of a woven or non-woven fabric that comprises a woven or non-woven fabric composed of polymer fiber and a reinforcement polymer having a greater strength and a slower rate of radiation-induced graft polymerization than said polymer fiber. Also, radiation graft treated stock prepared from said polymer substrate. In another aspect, a radiation graft treated material in the form of a woven or non-woven fabric material that is composed of polymer monofilament fiber of which only the surface has undergone a radiation-induced graft polymerization but of which the center remains unaffected by grafting. In addition, a method for performing radiation-induced graft polymerization on substrates in the form of webs of woven or non-woven fabric, which comprises the steps of exposing a substrate woven or non-woven fabric composed of polymer fiber to electron beams in a nitrogen atmosphere, contacting the irradiated substrate with a specified amount of monomer in a nitrogen atmosphere, and subjecting the monomer and the substrate in mutual contact to graft polymerization in a nitrogen atmosphere, characterized in that the first through third steps are performed in succession.

    摘要： 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.
