Abstract: The carbon paste electrode was used as the trace silver potential sensor. This electrode system exhibits a linear response over the range of 5× 10-7-1×10-2mol/L for trace of silver, and according to 1UPACrecommendation, the detection limit of this electrode system is 1 × 10-7mol/L. The electrode has been used to determine trace of silver in electroplate solution and fix solution with good results.
