ZnO NPs增敏流动注射化学发光法检测雨水中的H2O2
Detetmination of H2O2 intainwatet using flow injection chemiluminescence enhanced by ZnO nanopatticles
摘要
Abstract
Absttact:Based on the fact that the ZnO nanoparticles (ZnO NPs ) can enhance the weak chemilu-minescence (CL)of the luminol-H2 O2 system,a simple,fast and sensitive flow injection CL method was developed for the determination of H2 O2 in rainwater.Experimental parameters affecting CL were optimized,including pH and concentrations of ZnO NPs,luminol and H2 O2 .Under optimal conditions,the logarithm of CL peak area (lg A)is linear with the logarithm of the concentration (lg c)of H2 O2 when the concentration of H2 O2 ranges from 0.06 to 20μmol/L and its limit of detection is 0.016μmol/L(3σ).The method has been successfully applied to the determination of H2 O2 in rainwater,giving recovery rate in the range of 95%~102% and RSD (n= 11)of 2.41%.关键词
