摘　　要：利用火焰原子吸收光谱(FAAS)分析技术,对测定锑品中微量镉的基体和共存元素干扰、仪器分析参数等因素进行了研究,确定了最佳分析条件。试验结果表明:该方法准确、可靠、简便、适用。方法的检出限0.008 2μg/mL,相对标准偏差小于6%,回收率为92%～101%。Using the flame AAS technology,It studied the elements of the basis and interference from coexistence elements and instrument analytical parameters in determination of the content of cadmium in antimony products,and determined the best analytical condition.The results show that the way is accurate,reliable,simple and useful.The limit of detection of this way is 0.008 2 μg/mL,RSD of the measurement is less than 6% and recovery in range of 92%～101%.
