银离子选择电极测常量氰研究

Study on Macrocyanide Determination by Silver Ions Selective Electrode

向氰化液中加入银氰配离子，可使银离子选择电极测游离NaCN的线性响应上限大幅度提高．并对在高浓度氰化液中影响电极线性响应上限的其它因素如搅拌，电极制造工艺等进行研究．结果表明，电极法可直接用于氰化提金工艺中游离NaCN的测定．

When silver cyanide complex ions are added to the solution of cyanide the upper bound of linear response to silver ions selective electrode will be markedly increased. In high concentration of cyanic solution . the other factors influencing the upper bound of linear response to electrode , such as agitation, the technology of electrode processing are also investigated. The result displays that the electrode method can be directly used to determine frce sodium cyanide of the gold extraction by cyanidation.
