Zusammenfassung: | A chemiluminescence one-shot sensor for hydrogen peroxide is described. It is prepared by immobilization of cobalt chloride and sodium lauryl sulphate in hydroxyethyl cellulose matrix cast on a microscope cover glass. Luminol, sodium phosphate and the sample are mixed before use and applied on the membrane by a micropipette. The calibration graph is linear in the range 20–1600
μg/L, and the detection limit of the method (3
σ) is 9
μg/L. A relative standard deviation of 4.5% was obtained for 100
μg/L H
2O
2 (

11). The sensor has been applied successfully to the determination of hydrogen peroxide in rainwater. |
