摘要: Abstract The intensity of emitted light from CdSe quantum dots (QDs)–H2O2 is described as a novel chemiluminescence (CL) reaction for determination dysprosium. This based on the catalytic effect Dy3+ ions, causing significant increase in emission, result (QDs) with hydrogen peroxide. In optimum conditions, this method was satisfactorily by linear calibration curve range 8.3 × 10−7–5.0 × 10−6 M, detection limit 6.0 × 10−8 M, and relative standard deviation five determinations 2.5 × 10−6 M 3.2%. main experimental advantage proposed its selective to ions compared common coexisting cations, therefore, it successfully applied dysprosium water samples.
