    摘要: An aminophosphonic acid chelate resin, prepared by reacting an amino resin having amine-reactive groups (A) with an amino compound having one or more primary and/or secondary amino groups (B) to produce an aminated resin and subsequently reacting thus produced aminated resin with an alkylphosphonation agent (C), shows excellent adsorption ability of metal ions having low atomic weights such as calcium ions, magnesium ions, etc., when applied to a solution having high salt concentration.
