| 摘 要： | 作者用银离子选择电极直接电位法测定水中微量及痕量CN~-。以Ag(CN)_2~-为指示剂,采用多次标准加入法和格氏作图法求出溶液中CN~-含量。此法比用氰离子选择电极灵敏度高,比用比色法简便快速。

| Abstract: | This paper reports the determination of cyanide at low concentration with the silver ion-selective electrode with Ag(CN)_2~- indicator by multiple standard addition method and the method of Gran's plot.Using this method,the CN~- contents in the samples of the polluted water from Fuzhou district were deter mined. It was found that this method is more simple and faster than the traditional colorimetric method. |
