摘要
利用银作倦化剂,邻菲啰啉作活化剂,催化分解亚铁氰化钾,并以离子选择电极测定分解产物之一的氰离子,其电位值(Ep)与一定浓度范围的银(Ⅰ)成良好的线性关系。
The catalytic disintegration of K_4Fe(CN)_6 has been carried out by using silver as catalyst and o-phenathroline as activator. The ion seleotive electrode has been applied to determining cyanic ion, which is one of the disintegration product. The potential (E_p) is good linear to 1gC of silver. Therefore, the trace amouts of silver can be determined in the ore, and relative standard deviation is 4.33％, 3.81％ and 4.72％ respectively.
