摘要
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。
A new method for the chemiluminescence determination of cyanide has been proposed with CN^--luminol system. The method permits selective determination of cyanide with a detection limit of 1.2ng/ml for CN^-, The linear range is 2～100ng/ml for CN^-. The relative standard deviation is less than 4％. This method is applicable to the determination of cyanide in natural water and industrial waste water. The reaction mechanism is also discussed.
