摘要: 采用Zorbax C18色谱柱(5 μm,150 mm×4.6 mm)于40 ℃下分离十溴二苯乙烷产品,以甲醇-四氢呋喃(体积比为70∶30)为流动相,在230 nm波长下检测。实验结果显示,在十溴二苯乙烷的质量浓度为0.001~0.100 g/L时,其浓度与峰面积有较好的线性关系。该方法对十溴二苯乙烷的回收率大于96%,相对标准偏差为4.0%,可替代热分析法分析十溴二苯乙烷,且能满足工业生产检测的要求。

Abstract: A method was developed for the quantitative determination of decabromodiphenyl ethane (DBDPE) using high performance liquid chromatography (HPLC). The sample was separated on a Zorbax C18 column (5 μm, 150 mm×4.6 mm) at the temperature of 40 ℃ with the elution of methanol-tetrahydrofuran (70∶30, v/v) as mobile phase at a flow rate of 0.8 mL/min. The detection wavelength was 230 nm. The assay exhibited a good linearity in decabromodiphenyl ethane concentration range from 0.001 to 0.100 g/L with a correlation coefficient of 0.9991. The limit of detection was 0.2 mg/L. The recovery was more than 96%(n=4), and the relative standard deviation was 4.0%(n=6). This method can be applied in the industrialized production for replacing the thermal analysis.
