| titleOfInvention | A method and apparatus for detecting transition and rare earth elements in a matrix |
| abstract | A method and apparatus for the detection of selected trace transition elements, earth elements, or both, in an aqueous sample including the same, together with alkali metals, alkaline earth elements, or both, provide forn (a) flowing said sample through chelator means, comprising ion exchange means, under conditions for retaining substantially all of the transition elements and rare earth elements in said sample but for retaining only part of said alkali metals and alkaline earth metals in said sample, (b) flowing a first eluant through said chelator means capable of stripping and removing in a waste stream the retained alkali metals and alkaline earth metals, but not transition elements and rare earth elements from the chelator means, (c) flowing a second eluant through said chelator resin means to strip the retained transition elements and rare earth elements therefrom and form a chelator effluent stream, (d) flowing the chelator effluent stream from step (c) through concentrator means, comprising ion exchange means, to retain said transition elements and rare earth elements therein while passing the remainder of said chelator effluent stream, (e) discontinuing the flow of said chelator effluent stream to said concentration means, (f) passing a third eluant, comprising an aqueous solution of a chelator complex agent, through said concentrator means, under conditions to elute at least selected ones of said transition elements and rare earth elements in chelated complexes in a concentrator effluent stream, and (g) passing said concentrator effluent stream to a detector in which said selected transition elements and rare earth elements are detected. |
