ABSTRACT:
A reagent composition particularly adapted for use in treating organic samples suspected of containing chemically-bound heavy metals preparatory to electrically detecting and measuring the heavy metal content of the samples. The composition includes an electrolyte vehicle which is essentially free of the heavy metal being detected and measured, a measured quantity of at least one metal ion-containing reagent dissolved therein, said metal ion (1) being adapted to displace the heavy metal from its organic chemical bonding and (2) remaining in electrolytic solution at the electrolytic deposition potentials of the heavy metals being detected and measured, a dispersing agent, and a hydrogen ion source for adjusting the pH of said composition to pH about 1.
