液相色譜測飲用水中一氯乙酸和二氯乙酸
液相色譜測飲用水中一氯乙酸和二氯乙酸 詳細信息：

固定相：專用
規格：HH-LYS2019

一氯乙酸也稱氯乙酸，是一種化工原料，通常作為染料、醫藥、農藥、樹脂及其他有機合成的中間體，廣泛應用于工業生產中，該品劇毒，對人體有較大危害。工業污染是水體中產生氯乙酸的主要來源。二氯乙酸是飲用水在氯化消毒處理過程中產生的消毒副產物，它對人體具有潛在的致癌作用。因此，快速測定飲用水中的一氯乙酸和二氯乙酸已成為人們關注的重點。
已有文獻報道采用離子色譜結合固相萃取法測定飲用水中的氯乙酸，以碳酸鈉和甲醇作為流動相測定時，每個樣品約需要25 min；氣相色譜法可測定飲用水中氯乙酸含量；液相色譜法結合固相萃取可測定甜菜堿中的氯乙酸含量。此外，還有氣相色譜-質譜法、毛細管電泳法等。其中氣相色譜-質譜法需要進行衍生化，其衍生化試劑具有潛在危害性。
滕州市浩瀚色譜儀器技術服務有限公司，采用液相色譜法測定飲用水中的一氯乙酸和二氯乙酸的含量，外標法定量，結果滿意。

Determination of monochloroacetic acid and dichloroacetic acid in drinking water by liquid chromatography
Determination of monochloroacetic acid and dichloroacetic acid in drinking water by liquid chromatography

Stationary phase: dedicated
Specification: HH-LYS2019



Monochloroacetic acid, also known as chloroacetic acid, is a chemical raw material. It is commonly used as an intermediate in dyes, pharmaceuticals, pesticides, resins and other organic synthesis. It is widely used in industrial production. It is highly toxic and has great harm to the human body. Industrial pollution is the main source of chloroacetic acid in water. Dichloroacetic acid is a disinfection by-product of drinking water in the process of chlorination and disinfection, and it has potential carcinogenic effects on the human body. Therefore, rapid determination of monochloroacetic acid and dichloroacetic acid in drinking water has become a focus of attention.
It has been reported in the literature that the determination of chloroacetic acid in drinking water by ion chromatography combined with solid phase extraction is carried out. When sodium carbonate and methanol are used as mobile phases, each sample takes about 25 minutes. Gas chromatography can determine the content of chloroacetic acid in drinking water. High performance liquid chromatography combined with solid phase extraction can determine the chloroacetic acid content of betaine. In addition, there are gas chromatography-mass spectrometry, high performance capillary electrophoresis, and the like. Among them, gas chromatography-mass spectrometry requires derivatization, and its derivatization reagent is potentially harmful.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. used high performance liquid chromatography to determine the content of monochloroacetic acid and dichloroacetic acid in drinking water. The external standard method was used to quantify the results.
