CuFe2O4纳米粒子增敏Luminol-EDTA化学发光体系研究及应用
Enhancement of chemiluminescence of Luminol-EDTA system by CuFe2O4 nanoparticals and its application
摘要
Abstract
A new chemiluminescence system of Luminol-EDTA-CuFe2O4 NPs was firstly developed based on the fact that CuFe2O4 nanoparticals (NPs) could significantly enhance the chemiluminescence (CL) intensity of the Luminol-EDTA system.The UV-Vis spectra and the chemiluminescence spectra suggested that no new luminophor formed after the introducing of CuFe2O4 NPs in the Luminol-EDTA system.The possible mechanism of CuFe2O4 NPs participated in Luminol-EDTA system was proposed by combining with the property of CuFe2O4 NPs.Additionally,it was found that rutin could inhibit the chemiluminescence of the proposed Luminol-EDTA-CuFe2O4 NPs system.Combined with flow injection,the system was applied to the determination of rutin in rutin tablets.Under the optimal conditions,the relationship between the relative CL intensity and the logarithm of concentration of rutin was linear when the concentration of ratin ranged from 2 × 10-a mol/L to 2 × 10 5 mol/L with the detection limit of 1.21 × 10-9 mol/L.The recommended method has been successfully applied to the determination of rutin tablets and the recovery was between 97％-102％ and RSD (c=1×10-7mol/L,n=11) was 2.54％.关键词
