Abstract:

The characteristic of cobalt catalysis chemiluminescence of 9, 10-dimethyl acridinium fluorosulfonate (DMAF) in basic H2O2 solution was studied. A new chemiluminescent system (DMAF-H2O2-CO2+) was established and used to determine cobalt in tap water, river water and pond water. Linear calibration range was 1.0 × 10-10 ∼ 1.0 × 10-7 g/mL. The detection limits was 5.0 × 10-11 g/mL. RSD was 6.0% for 5.0 × 10-9 g/mL CO2+ (n = 6). Interference ions were examined. The precision, accuracy and selectivity of the method are satisfactory.
