荧光法在目前水质石油类测定分析方法中,干扰成分主要有:苯酚、LAS、S、邻硝基酚、四氯化碳、三氯甲烷、硝基苯、丙酮等。荧光法测定过程中萃取剂中的干扰有机物在特定波长的吸收效果要比紫外法和红外法少。因为萃取剂中的有机物对紫外光和红外光有吸收的物质大多不产生荧光,尤其在激发状态下测定石油类的定量分析实验中,能产生荧光的干扰物质则会更少。实验部分主要仪器及试剂主要仪器:日本岛津生产的RF-520型荧光分光光度计;721
Fluorescence method in the current water quality determination of petroleum analysis methods, the main interference components: phenol, LAS, S, o-nitrophenol, carbon tetrachloride, chloroform, nitrobenzene, acetone and so on. Fluorescence method of extraction process interference organic matter at a specific wavelength absorption effect than the UV method and the infrared method less. Because the extractant of organic matter on the UV and infrared light absorption of most of the material does not produce fluorescence, especially in the determination of the state of the excited state of the oil quantitative analysis experiments, can generate fluorescent interference material will be less.
