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.
