Abstract

The invention discloses a method for detecting 1,3,5-trichlorobenzene in water quality. The method includes the step that sample water is detected through a purge-and-trap series connection gas phasechromatography-mass spectrometry spectrometer. According to the method for detecting the 1,3,5-trichlorobenzene in the water quality, the gap of the detection field is filled, and the requirements ofcustomers who have the detecting demand in existing markets are supplemented; the detection low limit can reach 0.04 [mu]g / L; the purge-and-trap series connection gas phase chromatography-mass spectrometry spectrometer is adopted, the complex pretreatment process is eliminated, the repeatability and reproducibility are better, and operation is easy and convenient; meanwhile, use of a great numberof organic reagents is eliminated, and the environment is protected advantageously; through a GCMS purge-and-trap measurement method, an extraction reagent is not required, the risk of exposure by testers is lowered, and meanwhile, the cost of waste liquid treatment is greatly lowered; and in addition, the dosage of the reagents is decreased, and thus the influence on the environment in the wasteliquid treatment process is also lowered.

Description

technical field [0001] The invention relates to the detection field, in particular to a method for detecting 1,3,5-trichlorobenzene in water quality. Background technique [0002] 1,3,5-Trichlorobenzene is insoluble in water, slightly soluble in ethanol, easily soluble in ether and benzene, widely used in the preparation of pesticides, fuels, medicines, electrolytes, lubricants, etc., for organic synthesis, insecticide Synthesis of agents and dyes. This substance is irritating, can cause conjunctivitis, rhinitis, and has an inhibitory effect on the central nervous system. Long-term exposure can cause liver and kidney damage. Because 1,3,5-trichlorobenzene is stable and harmful to human health, it is considered as a persistent organic pollutant. [0003] At present, 1,3,5-trichlorobenzene in water quality is mainly detected by clause 24 of Chapter 8 of GB / T 5750-2016 "Standard Examination Methods for Drinking Water". This method is extracted with petroleum ether and purifie...
