摘要
该文建立的顶空-气相色谱法测定水中苦味酸的方法,使得水样中的苦味酸经次氯酸钠氯化衍生后,直接顶空进样,保留时间定性,外标法定量,得到了良好的分离效果和较高的灵敏度和精密度。该方法简便、快捷,能达到GB/T 5750.8-2006中规定的要求。
The analytical methods of Picric Acid in water were studied by Headspace-Gas chromatography. Picric Acid in water was derivatized through javet,the derivative product was directly determined by HS-GC,haracterized with retention time and quantified with external standard method. The high precision and high sensitivity can be acquired. These methods can completely meet the requests of GB/T 5750.8-2006.
