摘要
甲醛是环境中普遍存在的化学污染物质.车内相关环境中也存在甲醛,因此需要对甲醛的浓度进行测定,以达到治理污染的目的.本文利用 3-甲基-2-苯并噻唑啉酮腙盐酸盐法(MBTH)和高效液相色谱法(HPLC)对汽车内饰挥发的甲醛进行比较测试,发现MBTH法在试验条件下可以快速测得甲醛浓度,使用便捷、实用性较强.但针对各种汽车内饰零件挥发形成的复杂空气环境,甲醛的定性定量测定以HPLC法为佳.
Abstract
Formaldehyde is a common chemical pollutant in the environment.Formaldehyde is also pre-sent in the relevant environment in the car,so the concentration of formaldehyde needs to be measured to achieve the purpose of pollution control.In this paper,3-methyl-2-benzothiazolinone hydrazone hydrochlo-ride method(MBTH)and high performance liquid chromatography(HPLC)were used to compare and test formaldehyde volatilization in automotive interior.It was found that MBTH method can quickly measure formaldehyde concentration under experimental conditions,and it is convenient to use and practical.Howev-er,in view of the complex air environment formed by volatilization of various automotive interior parts,HPLC method is the best method for the qualitative and quantitative determination of formaldehyde.
