Scope

This method is suitable for the determination of metal ion impurities in common chemical reagents and high-purity chemical reagents, especially zinc, cadmium, lead and copper. Sensitivity can reach ppb level. This method can continuously determine several impurities in one determination process. This general rule only stipulates the two-electrode system with silver-based mercury film electrode as the working electrode and the silver-silver chloride electrode as the reference electrode and the three-electrode system with the addition of the counter electrode. This general rule adopts the linear displacement dissolution method.
