Abstract:
Objective To establish a rapid method having great capability for enrichment and anti-interference, higher sensitivity and good precision for determination of trace silver in drinking water. Methods The conditions of determination such as the definition of peak potentials, the selection of auxiliary electrolytes, the selection of kind and amount of oxidants and anti-interference test were carried out by MP-1 potentiometer using glass-carbon electrode. Results The lowest detection limit, average recorery rate and average relative standard deviation were 0.004 ug/ml, 100.3% and 2.73% respectively. Conclusion This method was suitable for determination of trace silver in drinking water.
