发明名称 Ion exchange resin having dual morphology
摘要 The invention provides a method for removing metal oxides and colloidal material from high-resistivity water streams at a relatively high removal efficiency. The method includes hydrating a highly ionized dual morphology ion exchange resin in a macroreticular, desiccated morphology to produce a macroreticular, hydrated morphology. A water stream which is brought into contact with the resin is purified. The water stream may, optionally, also be contacted with both a cation exchange resin and an anion exchange resin. The invention additionally provides a method for selecting ion exchange resins which are particularly suited for use in removing metal oxides from a condensate stream. The method serves to narrow the field of candidates for pilot-scale resin testing with industrial water streams.
