摘要
目的:研究红薯中硒含量的最佳测定方法。方法:采用湿法消解,微波消解处理样品,原子荧光光谱法进行硒的测定。结果:硒含量在0~10μg/L内呈现良好的线形关系,相关系数0.999 9,最低检出限为0.032 8μg/L。结论:用该方法测定红薯中硒的含量,方法的线性关系、精密度、准确度及加标回收均得到满意结果,微波消解优于湿法消解。
Objective： A best method for the determination of selenium in sweet potato. Methods： The sample was dissolved with wet digestion and microwave digestion, the selenium was determined by atomic fluorescence spectrometry. Results： The concentration of selenium was linearly in the range of 0-10 μg/L, the linear correlation coefficient was 0.999 9, the detection limit was 0.032 8 μg/L. Conclusion： The method for determination of selenium in sweet potato, linearity, precision, accuracy and standard addition recovery are satisfactory, microwave digestion is better than that of wet digestion.
