Abstract

The invention relates to a detecting method for the water-quality phenolic compound content. The method includes the following steps of (1) extracting to-be-derived sample liquid; (2) conducting derivatization of a sample, wherein 100 microliters of a first derivatization agent is added into the to-be-derived sample liquid, the mixture is reacted for 1 h at the room temperature, and then is put into a GC-MS and detected and analyzed, and the first derivatization agent is BSTFA; (3) conducting derivatization of a standard working solution; (4) calculating the concentration. According to the detecting method for the water-quality phenolic compound content in the embodiment, by changing the steps of the to-be-derived sample liquid and the derivatization agent, the peaking effect is better, and the steps that the temperature is increased to replace a solvent does not need to be conducted during derivatization; compared with the national standard, the detecting method is easier, and the used derivatization reagent is cheaper in price and higher in cost performance.

Description

technical field

[0001] The invention relates to the technical field of water quality detection, in particular to a method for detecting the content of phenolic compounds in water quality. Background technique

[0002] Phenol pollution in water is mainly phenol-containing wastewater discharged by some industrial enterprises, such as coking, papermaking, plastics, dyes, drugs, herbicides, pesticides, wood processing and many other industries. When the concentration of phenol in the water reaches 0.1-0.2mg / At L, the fish living in this kind of water body will contain phenols. If people eat this kind of fish and the amount of phenols ingested exceeds the detoxification ability of the body, chronic poisoning will occur, such as headache, dizziness, vomiting, Diarrhea, nervous disorder, anemia and other symptoms, using polluted water as drinking water, under the action of chlorine gas for disinfection to form chlorophenol, its taste is enhanced by one to two orders of magnitude t...
