Abstract
An atomic fluorescence spectrometry for the determination of micro arsenic in animal liver was developed with high sensitivity and fine accuracy. Under the selected experimental conditions, there was a linear relationship between the fluorescence intensity and arsenic concentration in the range of 0-160 ng.mL-1 with correlation coefficient of 0.9996. The limit of detection was 0.4 ng.mL-1, and the recovery was 94.2%-98.5%.
摘要
建立了一种用于测定动物肝脏中微量砷的原子荧光光谱法，该方法具有高灵敏度和良好的准确度。在选定的实验条件下，荧光强度与砷浓度在0 - 160 ng·mL⁻¹范围内呈线性关系，相关系数为0.9996。检出限为0.4 ng·mL⁻¹，回收率为94.2% - 98.5%。
