摘　　要：火焰光度分析技术是一种能够快速灵敏检测硫、磷等元素的成熟方法。在环境检测,农残检测,工农业生产领域得到广泛应用。通过对传统火焰光度检测器的改进设计,采用光栅和CCD传感器阵列作为检测器的光电转换器件,拓展了检测化合物的种类,成功实现了对H2S,PH3,NH3,AsH3,Cl2为代表的硫、磷、氮、砷、氯五种元素的实时检测。由原来依靠特征波长检测拓展到利用物质火焰光度光谱信息进行定性定量分析。结合化学计量学的方法有望成为一种能够同时检测多类有毒有害气体的快速现场检测技术。Flame photometric analysis technology has been proven to be a rapid and sensitive method for sulfur and phosphorus detection.It has been widely used in enviro nmental inspections,pesticide detection,industrial and agricultural production.By improving the design of the traditional flame photometric detector,using grating and CCD sensor array as a photoelectric conversion device,the types of compounds that can be detected were expanded.Instead of a single point of characteristic spectral lines,full spectral information has been used for qualitative and quantitative analysis of H2 S,PH3,NH3,AsH3 and Cl2.Combined with chemometric method,flame photometric analysis technology is expected to become an alternative fast,real-time on-site detection technology to simultaneously detect multiple toxic and harmful gases.
