| 摘 要： | 本文用塞曼效应石墨炉原子吸收法测定铍，以抗坏血酸作基体改进剂，使测定铍的灵敏度提高，并且提高了灰化温度和降低原子化温度，增强抗干扰能力。利用抗坏血酸的增感作用直接测定了渗透水和水系沉积物中的痕量铍。

Determination of Beryllium in Osmotic Water by Graphite Furnace Atomic Absorption Spectrometry |
| |
| Abstract: | This paper describes a method to determine beryllium by zeeman graphite furnace AAS using ascorbic acid as that matrix modifier.It not only enhances the sensitivity and increases the ashing temperature but also decreases the atomization temperature and reduces the interference.The method has been used for the determination of trace beryllium in osmotic water and sediment. |
