| 摘 要： | 氰化物是广泛应用于工矿业的有毒化学物质,不同存在形式的氰化物具有不同的毒性和地球化学行为,因此测定环境样品中不同存在形式的氰化物具有重要意义。总体而言,简单氰化物、总氰化物的分析技术相对成熟,而络合氰化物的分析逐渐成为氰化物测定中的难点和重点。本文主要对环境样品氰化物分析中的光度法(分光光度法、荧光法和原子吸收光度法)、电化学法(离子选择电极法、极谱法)、色谱法、放射化学法、流动注射分析法的原理、特点及分析效果进行详细的对比与讨论。

| Abstract: | Cyanides are used widely in agriculture and industry, including gold extraction, plastics production, electroplating, tanning and chemical synthesis, and expose high toxic risks to the environment. It is of significance to determine cyanide species beyond the total concentrations of cyanide, because various species of cyanides pose varying toxicity and have different environmental behaviors. The aim of this paper is to review the progress in cyanide determination in environmental samples by means of chromatography, spectrometry and flow injection analysis. |
