本文提出了利用鲁米诺-氰化物化学发光体系测定氰化物的新方法。方法的检出限是1.2ng/ml,校正曲线在2～100ng/ml CN~-范围内具有良好的线性。相对标准偏差小于4％。此方法已用于自来水和工业废水中氰化物的测定。文中对鲁米诺与氰化物化学发光反应的可能机理作了初步探讨。
This paper presents a new method for the determination of cyanide using luminol-cyanide chemiluminescence system. The detection limit of the method is 1.2ng / ml, and the calibration curve has a good linearity in the range of 2 ~ 100ng / ml CN ~ -. The relative standard deviation is less than 4%. This method has been used for the determination of cyanide in tap water and industrial wastewater. The possible mechanism of luminol reaction with cyanide chemiluminescence was discussed in this paper.
