MAKROZYKLISCHE LIGANDEN, AN SILIZIUMOXYD ODER KIESELGEL GEBUNDEN, UND DEREN VERWENDUNG ZUM SELEKTIVEN UND QUANTITATIVEN ENTFERNEN UND KONZENTRIEREN VON IN GERINGER KONZENTRATION GEGENWAERTIGEN IONEN AUS ANDEREN IONEN ENTHALTENDEN MISCHUNGEN.

摘要

The invention has composition of matter and process aspects. The composition of matter aspect relates to certain macrocyclic compounds bonded to silica or silica gel. The process aspect involves the use of any of these compositions of matter packed in a column through which a solution of the multiple ions is flowed to complex with the macrocyclic compound and separate a desired selected ion from a multiple ion solution, breaking the complex by flowing a receiving liquid through the column to free the desired ion and recovering the freed desired ion from the receiving liquid.
