应用AFS - 2 30型双道原子荧光光谱计进行了氢化物发生原子荧光光谱法测定西红花柱头中硒的研究 ,方法中采用硝酸做介质 ,并对各种最佳分析条件进行了测定。线性范围为 1.5～ 15 μg/L ,相关系数R =0 .9999,回收率为 90 %～ 97%。采用标准曲线法对 4种不同产地的西红花干燥柱头中硒进行了测定。该方法操作简单、快速 ,精密度好 ,准确性高 ,检出限较低 ,经济 ,便于推广应用。 AFS - 2 30 dual - channel atomic fluorescence spectrometer was used to study the determination of selenium in the safflower by hydride generation atomic fluorescence spectrometry. Nitric acid was used as the mediator and the best analytical conditions were determined. The linear range was 1.5-15 μg / L, the correlation coefficient R = 0.9999, the recovery was 90% -97%. The standard curve method was used to determine the selenium content of saffron stem stigma in four different habitats. The method is simple, rapid, precise, high accuracy, low detection limit, economical, easy to promote the application.
