摘要：
Flow injection analysis with on-line ion-exchange preconcentration using a mini-column loaded with 8-quinolinol immobilized on controlled-pore glass, is described for the determination of iron(II)-enhanced chemiluminescent oxidation of luminol in alkaline hydrogen peroxide. The detection limit for iron(II) is 10-13 mol/l (in 3 ml of sample). The operating conditions are optimized, and the effect of interferents is studied. The analysis time was 5 min for each sample, including 2 min for sample loading. © 1990 Springer-Verlag.
