| 中文摘要: |
| 选择邻苯二甲酸二甲酯(DMP)、邻苯二甲酸二乙酯(DEP)、邻苯二甲酸二丁酯(DBP) 3种标准物质为研究对象，建立了高效液相色谱法检测邻苯二甲酸酯的条件，对实验方法的准确程度进行了分析。结果表明，以甲醇-水为流动相，采用梯度模式洗脱，检测波长为225 nm，柱温为30 ℃，流量为1.000 mL/min，进样量为10 μL时，可以很好地分离3种邻苯二甲酸酯，目标分析物质量浓度在0.5～100 μg/mL范围之间时，得到的线性相关系数在0.999 96～0.999 98之间；重复性实验表明，10次实验的保留时间的相对标准偏差在0.0314%～0.0389%之间, 峰面积的相对标准偏差在0.0942%～0.353%之间，DMP,DEP,DBP的方法检测限分别为0.0228,0.0277,0.0489 μg/mL。 |
| 英文摘要: |
| Detection condition for phthalate was established by using standard phthalates as study objects including dimethyl phthalate, diethyl phthalate and dibutyl phthalate by High Performance Liquid Chromatography. The accuracy of the method was analyzed. The results showed that three kinds of phthalate can be well separated with a mobile phase of methanol water in gradient elution mode at the flow rate of 1 mL/min, in which wavelength 225 nm, column temperature 30 ℃, sample amount 10 μL; under the selected conditions, the correlation coefficients were in the range of 0.999 96～0.999 98 when the concentrations of the analytes are between 0.5～100 μg/mL; the relative standard deviation of retention time is between 0.0314%～0.0389%; the relative standard deviation of peak area is between 0.0942%～0.353%; the detection limit of DMP, DEP, and DBP is 0.0228 μg/mL, 0.0277 μg/mL, and 0.0489 μg/mL respectively. |
