Article Preview

Due to an enhancement effect of Lumino-KBrO3 chemiluminescence system induced by nitrite, nitrite in sauerkraut was determined using chemiluminescence method. The effects of reaction substance concentrations, acidity, and interfering ions on chemiluminescence system were investigated to explore the optimal conditions for nitrite determination. Results revealed that the optimal reaction conditions of chemiluminescence were 0.05MH2SO4, 0.06MKBrO3, 1.50×10-4MLuminol and 0.25MNaOH in the chemiluminescence system. The detection limit (S/N=3)for NO2-was 8×10-11g/mL and an excellent linear relationship was exhibited in the range of 0.001-10mg/L. Eleven replicate determinations for nitrite in sauerkraut at 1.00mg/kg exhibited an average recovery rate of 101.00% and a relative standard deviation of 2.90%. Therefore, it revealed that the method not only possessed high sensitive and selective characteristics, but also possessed rapid, simple and convenient characteristics, compared with traditional methods.
