In the present study, various metal peroxides nanoparticles such as ZnO2, CaO2, CdO2 and BaO2 are prepared by precipitation method without carbonates impurity. We studied the effect of these peroxide nano systems for Luminol driven Chemiluminescence detectionFe2+/Fe3+ < 0.02 mmol in alternative H2O2. In comparison, CaO2 peroxide was shown more intense Chemiluminescence than other peroxides and conventional aqueous H2O2 as well. It was observed that the detection limit was lower for CaO2 than other peroxide system and wider linear range was developed. This study would be most useful for the detection of iron in criminology and in Analytical chemistry with most stable CaO2.
