| 中文摘要: |
| 建立了一种同时测定水中碘化物和草甘膦的离子色谱方法,并对色谱条件进行了优化。采用瑞士万通A SUPP 5-150阴离子分析柱,以8 mmol/L碳酸钠为流动相,采用电导检测器实现了碘化物和草甘膦的同时分离和检测。在优化的色谱条件下碘化物检出限可达0.4 μg/L,草甘膦检出限可达1.3 μg/L,加标回收率为80.0%~120%。这一检测技术在水中碘化物和草甘膦中的应用操作流程少,步骤简单,同时具备较高的检测效率,分离作用优势明显,分析速度快,灵敏度高。 |

| An ion chromatography method for simultaneous determination of iodide and glyphosate in water was established,and the chromatographic conditions were optimized.Using Metrohm A SUPP 5-150 anion analysis column,8 mmol/L sodium carbonate as the mobile phase,the simultaneous separation and detection of iodide and glyphosate were achieved by the conductance detector.Under optimized chromatographic conditions,the detection limit of iodide could reach 0.4 μg/L,the detection limit of glyphosate could reach 1.3 μg/L,and the recovery rate was between 80.0% and 120%.The application of this detection technology in iodide and glyphosate in water has few operational procedures,simple steps,high detection efficiency,obvious separation advantages,fast analysis speed,and high sensitivity. |
