高效液相色谱法分析十溴二苯乙烷产品

Determination of decabromodiphenyl ethane using high performance liquid chromatography

采用Zorbax？C18色谱柱（5μm，150mm×4.6mm）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230nm波长下检测。实验结果显示，在十溴二苯乙烷的质量浓度为0.001~0.100g/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。

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 0.999 1.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.
