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(xì)信息：

固定相：專用
規(guī)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(yī)藥、農(nóng)藥、樹脂及其他有機(jī)合成的中間體，廣泛應(yīng)用于工業(yè)生產(chǎn)中，該品劇毒，對(duì)人體有較大危害。工業(yè)污染是水體中產(chǎn)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(chǎn)生的消毒副產(chǎn)物，它對(duì)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(guān)注的重點(diǎn)。
已有文獻(xiàn)報(bào)道采用離子色譜結(jié)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(dòng)相測定時(shí)，每個(gè)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(jié)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(zhì)譜法、毛細(xì)管電泳法等。其中氣相色譜-質(zhì)譜法需要進(jìn)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(shù)服務(wù)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(biāo)法定量，結(jié)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.
