Determining Trace Selenium in Water with Atomic Absorption Spectrometry of Graphite Tube Coated by Palladium

钯涂层石墨 管原子 吸收光谱法测 水中微量硒

The deviation between the model and experimental data of ammonia water falling-film absorption on a smooth vertical tube was not more than 10 % in the turbulent flow zone and 15 % in the non-turbulent flow zone .

理论数据与 氨水光 管降膜 吸收实验数据相比较，偏差在非湍流区不超过10%，在全湍流区不超过15%。

Thermodynamics analysis indicated that water absorption mass was relevant to both the water dipping temperature and the temperature distribution along the nonel tube .

热力学分析表明，导爆管的 吸水量不但和浸水温度有关，而且和温度沿导爆 管的分布有关。
