PEG-20M/6201不銹鋼填充柱測定乙醛和丙xi醛詳細信息:
乙醛(CH3CHO)為無色易揮發(fā)液體,在常溫常壓下能放出刺激性蒸氣,為微毒物質(zhì),對中樞神經(jīng)的抑制作用比甲醛強,對人的毒副作用主要是刺激皮膚、粘膜和由呼吸道吸入蒸汽對人的神經(jīng)、肝臟等器官造成危害。丙xi醛(CH2CHCHO)為無色透明易揮發(fā)性液體,有特殊辛辣氣味,屬于高毒類物質(zhì)。
滕州市浩瀚色譜儀器技術服務有限公司,采用填充柱,該方法乙醛和丙xi醛的檢出限分別為0.001 2 mg/L、0.000 6 mg/L,相對標準偏差分別為3.5%~6.9%、2.9%~5.8%,加標回收率分別為91.6%~108%、92.0%~105%。與GB推薦使用的分析方法相比較,該方法具有操作簡便、靈敏度高、重復性好、基本上不消耗有機溶劑等特點,可滿足地表水和廢水中乙醛和丙xi醛的測定要求。

Determination of acetaldehyde and propio nyl aldehyde with PEG-20M/6201 stainless steel packed column
PEG-20M/6201 stainless steel packed column for determination of acetaldehyde and propionaldehyde. Details:
Acetaldehyde (CH3CHO) is a colorless and volatile liquid. It can emit irritating vapors under normal temperature and pressure. It is a slightly toxic substance. It has a stro nger inhibitory effect on the central nervous system than formaldehyde. Its toxic and side effects on humans are mainly irritation to the skin, mucous membranes and Inhalation of steam from the respiratory tract causes harm to human nerves, liver and other organs. Propyl aldehyde (CH2CHCHO) is a colorless, transparent and volatile liquid with a special pungent odor and is a highly toxic substance.
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. uses packed columns. The detection limits of this method for acetaldehyde and propio nyl aldehyde are 0.0012 mg/L and 0.0006 mg/L, respectively, and the relative standard deviations are 3.5%~6.9%. , 2.9%~5.8%, and the recovery rates of standard addition are 91.6%~108%, 92.0%~105%. Compared with the analytical method recommended by GB, this method has the characteristics of simple operation, high sensitivity, good repeatability, and basically does not co nsume organic solvents. It can meet the determination requirements of acetaldehyde and propio naldehyde in surface water and wastewater.
