水体中苦味酸测定方法的研究与发展状况，阐述了每个分析方法的原理、测定条件、线性范围、检测限、干扰因素及消除方法、精密度和应用情况。为广大环保工作者的实际工作提供参考和借鉴。
浩瀚色谱（山东）应用技术开发有限公司将水样中的苦味酸氯化后，采用气相色谱法分离和检测水样中的苦味酸氯化产物。在Hh-5毛细管柱上，对苦味酸的氯化产物有较好的分离效果。方法快速、反应较为彻底，灵敏度高、精密度和准确度较好。
名称：毛细管柱
型号：HH-5
规格：30m*0.32mm*0.25um
zui高温度：300°C
应用：水质 苦wei酸的测定 气相色谱法
浩瀚色谱（山东）应用技术开发有限公司，采用《水质 苦wei酸的测定毛细管色谱柱岛津》建立了毛细管柱气相色谱-微池电子捕获检测器测定水中苦味suan的方法。水样中的苦味suan经次氯酸钠氯化衍生后,经正己烷提取后进行气相色谱分析。考察了萃取溶剂和次氯酸钠加入量对萃取的影响。在优化萃取条件下,苦wei酸在25~500μg/L范围内有良好的线性关系。

The research and development status of methods for determining picric acid in water bodies are discussed, detailing the principles, measurement conditions, linear range, detection limits, interfering factors and elimination methods, precision, and application scenarios of each analytical method. This provides references and insights for practical work by environmental protection professionals.
Hao Hanchrom (Shandong) Application Technology Development Co., Ltd. chlorinated the picric acid in the water sample and separated and detected the chlorinated products of picric acid in the water sample using gas chromatography. On the Hh-5 capillary column, the chlorinated products of picric acid exhibited good separation. The method is rapid, with thorough reactions, high sensitivity, and excellent precision and accuracy.
Name: Capillary column
Model: HH-5
Specifications: 30m * 0.32mm * 0.25um
Maximum temperature: 300°C
Application: Determination of Picric Acid in Water Quality by Gas Chromatography
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a method for determining bitter acid in water using capillary column gas chromatography with a micro-electron capture detector, based on the standard "Water Quality - Determination of Bitter Acid by Capillary Column Gas Chromatography (Shimadzu)." The bitter acid in water samples was derivatized by sodium hypochlorite chlorination, extracted with n-hexane, and then analyzed by gas chromatography. The effects of extraction solvent and sodium hypochlorite dosage on the extraction were investigated. Under optimized extraction conditions, bitter acid exhibited good linearity within the range of 25 to 500 μg/L.
