Application: HJ 676-2013 Water Quality Determination of Phenolic Compounds Liquid-Liquid Extraction/Gas Chromatography

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. proposed a method for the determination of phenolic substances in industrial wastewater. Under certain conditions, it was extracted with diisopropyl ether and then fully static and layered, and the organic phase was injected into gas chromatography. The chromatogram was obtained by the detector; the extraction conditions including pH, temperature, extraction time, extraction ratio and other factors were experimentally studied, and the phenolic substances in the water were qualitatively determined by gas-mass spectrometry, and established under the optimal extraction conditions. The analysis method was developed, and the experiment proved that the method has the advantages of high precision, high accuracy and low detection limit.
