建立了高效液相色谱测定三烯丙基异氰尿酸酯含量的分析方法。通过实验确定了最佳色谱条件,色谱柱:Ultmate-C18柱(250 mm×4.6 mm,5μm);柱温:25℃;流动相:V(甲醇)∶V(0.1 mol/L磷酸-磷酸二氢钠缓冲溶液(pH为3.0))=60∶40;检测波长:210 nm;流速:1.0 mL/min。结果表明,三烯丙基异氰尿酸酯的浓度在1.0～200.0 mg/L范围内线性良好,相关系数为0.999 9,平均回收率为99.33%,相对标准偏差为1.81%,最低检出限为0.2 mg/L,最低定量限为1.2mg/L。本法简便、快速、准确,重复性好,可有效测定三烯丙基异氰尿酸酯的含量。
A method for the determination of triallyl isocyanurate by high performance liquid chromatography was established. The optimal chromatographic conditions were determined experimentally by column: Ultmate-C18 column (250 mm × 4.6 mm, 5 μm); column temperature: 25 ℃; mobile phase: V (methanol) Sodium hydrogen buffer solution (pH 3.0)) = 60:40; detection wavelength: 210 nm; flow rate: 1.0 mL / min. The results showed that the linear range of triallyl isocyanurate was 1.0 ~ 200.0 mg / L, the correlation coefficient was 0.999 9, the average recovery was 99.33%, the relative standard deviation was 1.81%, the lowest detection limit 0.2 mg / L, the lowest limit of quantification was 1.2 mg / L. This method is simple, rapid, accurate, reproducible, and can be effectively measured triallyl isocyanurate content.
