摘要

As the limits imposed on heavy metal content in aqueous samples have become more stringent it has become necessary to devise more rapid and efficient preconcentration methods which maintain speciation. We propose to develop an on-line preconcentration method and device based on coulombic attraction between the charged form of a conducting polymer and ionic analytes in solution. Upon electrochemical conversion of the polymer back to its neutral, hydrophobic form, the analytes would be released within seconds into carrier stream for analysis by ICP/MS, HPLC/ICP-MS or FIA.
