摘要
红外分光光度法是测废水中石油类物质的国家标准分析方法,但仪器在使用过程中,满度会发生变化。满度的漂移对实验数据准确性的影响很大,尤其是低浓度水样。本文讨论了红外分光光度法测定水体中石油类物质满度对实验数据的影响。
Infrared spectrophotometry is national standard method to analyze petroleum derivatives in wastewater.During operation,span drift of instruments often happens,which affects the accuracy of the experimental data very much,especially for the water samples with low concentration.In this paper the effect of span drift on the experimental data in determination of petroleum derivatives in wastewater using infrared spectrophotometry was discussed.
