Triazines are widely used herbicides that can be detected in the environment at trace level. A preconcentration step is necessary to determinate them before analysis. In this study, carbonaceous and polymeric adsorbents are compared with C18 for the solid-phase extraction of simazine, atrazine, and propazine in water samples in order to quantitate their levels by high-performance liquid chromatography using photodiode-array detection.
三嗪类是广泛使用的除草剂，可在环境中以痕量水平被检测到。在分析之前，需要一个预浓缩步骤来测定它们。在本研究中，将碳质吸附剂和聚合物吸附剂与C18进行比较，用于水样中西玛津、莠去津和扑灭津的固相萃取，以便通过使用光电二极管阵列检测的高效液相色谱法定量它们的含量。
