非分散红外法测定废水中石油类物质的影响因素探讨

摘要

This paper expatiate the measuring principle of non-dispersive infrared analysis in petroleum determination in industry waslewalcr, and have a initial investigation on the focal and difficult points by using the non-dispersive infrared oil content analyzer, specifically analyzed the interference factors and elimination method of using the non -dispersive infrared oil content analyzer. It provided the basis to gain a more exact and reliable consequence and improve the accuracy of determine petroleum content.%阐述了工业废水中石油类物质的测定方法——非分散红外法,就目前使用的非分散红外测油仪的操作要点及其在使用过程中遇到的问题作了初步探讨,具体分析了非分散红外测油仪在实际使用中的化学药品、萃取过滤、仪器使用等干扰因素及消除办法,为得到更为准确、可靠的监测结果提供依据,提高了分析测定石油类物质含量的准确性.
