| 摘 要： | 建立了微量扩散-离子色谱/脉冲安培检测法(IC/PAD)用于测定工业废水中的氰化物。对于基质复杂的工业废水,先通过微量扩散法进行净化富集,再采用IC/PAD法对样品中的氰化物进行分析检测。在最佳条件下,氰化物在1.0~200.0μg/L范围内具有良好线性,工业废水中氰化物的检出限和定量限分别为0.15μg/L和0.50μg/L,方法加标回收率在88.6%~108.5%之间。本方法灵敏度高、快速安全、操作简便,为工业废水中氰化物的检测提供了一个新的选择。

| Abstract: | The industrial wastewater with complex matrix was purified and enriched by microdiffusion method,then the cyanide in the sample was analyzed by IC-PAD method.Under the optimal conditions,the linear range of cyanide was 1.0—200.0μg/L,the detection limit and the quantitation limit were 0.15μg/L and 0.50μg/L,respectively,the recoveries ranged from 88.6%to 108.5%.The proposed method was sensitive,rapid,safe and convenient. |
