| Abstract: | Ag(I) has catalytic effect on disintegration and oxidation of K4Fe(CN)6. The ion Selective electrode has been applied to determining cyanic ion, which is one of the disintegration product. The potential (Ep) is good linear to concentration of silver. Therefore, the trace amounts of silver can be determined, the detection limit is 4. 2ng/ml. The method can be used for water analysis with satisfaction. |
