No truly specific chelating resin has yet been reported. Even high selectivity for a particular metal is in most cases achievable only under fairly circumscribed conditions, e.g. of pH, ionic strength, nature of the co-ion(s) present, temperature, or absence of other too-strongly competing metal species. Attempts to improve the capability of known selective materials have led to the laboratory synthesis of sorbents many of which would be incapable of economic manufacture in the quantities required for the uses proposed. However, some commercial applications are discussed.
