在HP-5毛细管柱上，对苦味酸的氯化产物有较好的分离效果。
1·In the paper, a PVC membrane picric acid anion selective electrode is developed using Bromhexadecyl pyridine picrate ion pair as the active component and dioctyl phthalate as the plasticizer.
本文用苦味酸溴代十六烷基吡啶离子对作为电活性物质，以邻苯二甲酸二辛酯为增塑剂，研制成以PVC为基质膜的苦味酸离子选择电极。
2·The thermodynamics and dynamics for adsorption of picric acid onto polyamide under static conditions were studied and the influence of temperature on the adsorption was also inspected.
在静态下，考察了温度对聚酰胺树脂吸附水溶液中苦味酸的影响，探讨了吸附的热力学、动力学规律。
