ABSTRACT:
A system is provided for the detection of transition elements and/or rare earth elements in an aqueous sample which also contains high concentrations of alkali and alkaline earth metals. The system is effective for determination of transition elements and/or rare earth elements in sea water, industrial waste streams, biological fluids and biological issue samples.
