Our life is inseparable from drinking water. Under normal circumstances, only standard drinking water can meet our use requirements. Therefore, when judging whether drinking water meets the standards, it needs to be tested, because the water quality contains a variety of parameters, so it is necessary to use accurate methods for testing, and there are many methods for testing drinking water. Today, I will tell you what are the testing methods for drinking water. What are the detection methods for drinking water 1. Standard solid phase extraction/gas chromatography mass spectrometry is generally used to detect 15 kinds of semi-volatile organic compounds in drinking water. 2. When carbofuran, glyphosate, and bentazone exist in drinking water, liquid chromatography-mass spectrometry is generally used. 3. For the presence of bentazone, carbofuran, glyphosate, 2,4-D, atrazine, pentachlorophenol and methyl parathion in drinking water, use standard liquid chromatography tandem mass spectrometry. 4. When there are 11 kinds of phenyl urea pesticides in drinking water, the standard detection method of liquid chromatography tandem mass spectrometry is adopted. 5. Use high performance liquid chromatography when there are five pyrethroids in drinking water. 6. Capillary column gas chromatography is used when chlorothalonil exists in drinking water. 7. Use ion chromatography when glyphosate exists in drinking water. 8. When niclosamide exists in drinking water, use extraction-back extraction spectrophotometry. 9. Use high performance liquid chromatography when niclosamide exists in drinking water. Since the organic matter in drinking water is different, before testing the water quality, you can first determine what type it is, and then choose the corresponding method to test the drinking water quality. Under normal circumstances, you can get accurate data .
