气相分子吸收光谱法测定油田废水中硫化物的研究

使用气相分子吸收光谱法测定油田废水中硫化物,弥补了传统对氨基二甲基苯胺光度法的操作步骤复杂,受色泽度、易挥发及易沉淀干扰因素多,分析速度慢等的缺陷。气相分子吸收光谱法在测定油田废水实际样品时具有高灵敏度、高精密度、快速检测得出良好实验结果等优势,带有均质吹扫功能的进样器直接把加固定剂的硫化物水样进行均质,是油田废水测定硫化物浓度快速有效的检测方法。

The gas phase molecular absorption spectroscopy was applied in the determination of sulfide in oilfield wastewater,which compensated the defects of traditional N,N-Dimethylphenylenediamine photometric method of the complex steps,interference factors and slow analysis speed.The results showed that this method is sensitive,accurate and with good effect in experiment.
