| 摘 要： | 研究了冷蒸气发生-原子吸收光谱法测定日用陶瓷浸泡液中痕量镉的反应体系。对载气流速、NaBH4浓度、增敏剂加入量和介质酸度的影响,以及基体和共存离子的干扰进行了考察。将该方法与石墨炉原子吸收光谱法进行比较。方法简便快速,回收率为94.0%~104.9%,相对标准偏差(RSD,n=7)小于3.6%。方法具有快速、准确、灵敏度高、经济实用等优点,用于陶瓷浸泡液中痕量镉的测定,结果令人满意。

| Abstract: | Trace cadmium in soaking solution of domestic ceramics was determined by cold-vapor generation atomic absorption spectrometry.The factors affecting the determination,such as flow rate of carrier gas,concentration of NaBH4(sodium boron hydride),amount of sensitizer added,acidity and interference from coexisting ions were tested.The recovery of the method for Cd is in the range of 94.0%～104.9% with precision of less than 3.6%RSD(n=7).Compared to GF-AAS,the method provides the advantages of high sensitivity and accuracy,high efficiency,economy and practicality.The method has been used in the determination of trace cadmium in soaking solution of domestic ceramic with satisfactory results. |
