Abstract

Laser Raman spectroscopy technique based on Raman scattering theory has the advantages of rapid,nondestructive,and without sample pretreatment.25samples of benzene with different concentrations are studied by using laser Raman spectroscopy technique.The results show that in the 184.8g/L~0.264g/L concentration range,the linear relationship between the intensity of Raman lines of benzene and its concentration.The linear correlation coefficient of R=0. 99626is obtained by using the least square method.The detection limit is 0.223g/L.

激光拉曼光谱法检测低浓度苯

基于拉曼散射理论的激光拉曼光谱技术具有快速、无损、无需样品预处理等优点。用激光拉曼光谱技术对25个不同浓度苯样品进行了研究。结果表明:在184.8g/L~0.264g/L浓度范围内，苯的拉曼谱线强度与浓度呈线性关系;线性相关系数R=0。99626是用最小二乘法得到的。检出限为0.223g/L。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
