摘要:
建立了用高效液相色谱同时测定电合成反应液中喹啉酸和喹啉含量的方法.采用Hypersil C18(150 mm×4.6 mm i.d)型色谱柱;流动相为甲醇-磷酸盐缓冲溶液;检测波长254 nm;柱温30℃;流速0.9 mL· min-.结果表明,喹啉酸和喹啉在上述色谱条件下分离效果较好,两种物质的质量浓度线性范围分别为0.09 ～0.89 g·L-1和0.10～0.92 g·L-1,检出限分别在0.88×10-3 g·L-1和1.16×10-3 g·L-1,加标回收率分别在98.4％ ～ 102.0％和98.80％ ～ 99.70％,测定结果的最大相对标准偏差分别为0.70％和0.56％.
Abstract:
A method was presented for the simultaneous determination of quinolinic acid and quinoline in theelectrochemical synthesis reaction liquid by high performance liquid chromatography ( HPLC). The analysiswas performed on a Hypersil C18 column with a mixture of V( methanol ):V( phosphate buffer solution with0.1% tetrabutyl ammonium hydroxide ,pH =7.0) = 50:50 as the mobile phase at a flow rate of 0.9 mL ·min’. The samples were detected at 254 nm with an UV detector and the column temperature was 30 ℃. Itwas found that quinolinic acid and quinoline could be well separated under the chromatographic conditions.The linear range of the mass concentration were 0.09 ~0.89 g·L ’ and 0.10 g·L-’ ~0.92 g ·L respec-tively. The recoveries for them were 98.4% ~ 102.0% and 98.80% ~ 99.70%. The maximum relativestandard deviations were 0.70% and 0.56% for quinolinic acid and quinoline.
