摘要
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.
