System for detecting transition and rare earth elements in a matrix |
| abstract |
A method for the detection of trace transition elements and rare earth elements in a sample also containing alkali metals or alkaline earth elements. The sample is flowed through a chelator column which retains the transition elements and rare earth elements. Then a first eluent (e.g. ammonium acetate) is passed through the column to strip the alkali and alkaline earth metals retained on the column. Then a second eluent (e.g. a strong acid) is passed through the chelator column to remove the transition elements in a chelator effluent which flows through an ion exchange resin concentrator to retain only the transition elements and rare earth elements. Then, a chelator complexing agent (e.g. pyridine-2,6 dicarboxylic acid or an oxalate) flows through the concentrator column to remove the transition elements and rare earth elements. |
