Polytetraalkylammonium containing ligand bound politetraalquilamina and inorganic supports and methods of using them to separate and concentrate desired ions from solutions.

摘要

A method for extraction and ion concentration DESIRED OF A SOLUTION STRONG may contain higher concentrations of other ions containing H ELEVATED + comprises contacting SOLUTION SOURCE WITH A compound comprising a ligand containing polytetraalkylammonium AND / OR polytrialkylamine covalently bound THROUGH A GROUP SEPARATOR ORGANIC SILICON TO A SUPPORT inorganic solid. The party or parties polytetraalkylammonium AND / OR COMPOSITE polytrialkylamine has an affinity desired ions to form a RETRIEVING ASI desired ions from solution SOURCE. THE DESIRED IONS ARE EXTRACTED COMPOUND contacting the compound with a much smaller volume of a receiving solution having higher affinity PART THAT DESIRED IONS Ligand polytetraalkylammonium AND / OR COMPOSITE polytrialkylamine. CONCENTRATES IONS thus extracted can be recovered by known means. Esutil PROCESS IN IONS EXTRACTION OF UNWANTED OR UNWANTED AND DRAFTS IN TREATING waste streams. The invention also relates to ligands AND CONTAINING polytetraalkylammonium polytrialkylamine covalently bonded THROUGH A GROUP SEPARATOR MATERIAL SUPPORT TO A solid inorganic.
