索氏提取－高效液相色谱法测定大气颗粒物中的十溴联苯醚
Determination of Decabrominated Diphenyl Ether in Gas Particle Samples Using Soxhlet Extract Method Followed by High Performance Liquid Chromatography
摘要
Abstract
A new method was developed to determinate decabrominated diphenyl ether ( decaBDE) in gas particle samples.The samples were extracted by Soxhlet method to accumulate decaBDE, and analyzed using high performance liquid chromatography ( HPLC) with ultra-variable wavelength ( UV) detector.The optimum conditions were attained as follows:the extracted reagent was a mixture of acetone and hexane (the ratio of 1∶2), and extracted time was 48 h. A ODS-BP C18 column was used, methanol-water (97∶3) was used as mobile phase, the flow rate was 1.0 mL/min,the wavelength of detector was 226 nm.Linearity was observed well as y =1.783 1x+13.248 in the range of 10 ~200μg/g, and the coefficient of correlation (R2) was 0.997 6.The average recoveries ranged from 90.0% to 103.3%, and the relative standard deviations (RSD) were less than 5.0%.The limit of detection (LOD), was 0.53μg/g, and the limit of quality (LOQ) was 1.77 μg/g.关键词
