建立了流动相化学发光结合控释技术测定铅的方法。通过静电作用将化学发光试剂鲁米诺和高锰酸钾固定在阴离子交换树脂上。铅离子对鲁米诺与高锰酸钾的化学发光反应有增敏作用。用磷酸钠溶液从阴离子交换树脂柱上洗脱鲁米诺和高锰酸钾。该体系的线性范围为10μg m L−1，检出限为5 × 10-9g m L−1铅(3σ)。在1min内完成分析，相对标准偏差为3.2%(1.0 × 10-7g mL−1，n= 9)。该柱具有显著的稳定性，可重复使用350次以上，重复使用21天。该方法已用于人体血样中铅的测定。
A flow-through CL method for the determination of lead combined with controlled-reagent-release technology has been developed. Chemiluminescence (CL) reagents luminol and potassium permanganate were immobilized on anion exchange resin by electrostatic interaction. Lead ion was determined by its enhancing effect on the CL reaction between luminol and potassium permanganate. Both luminol and potassium permanganate were eluted from the anion exchange resin column by sodium phosphate solution. The linear range of the system was 10 μg mL−1, and the detection limit was 5 × 10–9g mL−1lead (3σ). A complete analysis could be performed in 1 min with a relative SD 3.2% (1.0 × 10–7g mL−1,n= 9). The column shows remarkable stability and can be reused over 350 times and 21 days. The method has been applied to determine lead in human blood samples.
