甲醇是*简单的饱和一元醇,也是重要的化学工业基础原料和清洁液体燃料,广泛应用于有机合成、医药、农药、涂料、染料、汽车和国防等工业中。甲醇毒性较大,误饮或长期接触都会引起中毒,因此国家相关标准对空气中甲醇含量和污染源甲醇排放浓度都作了相应规定。相应的甲醇监测方法有HJ/T 33-1999和《空气和废气监测分析方法(第四版增补版)》[的气相色谱法和分光光度法。

Methanol is the simplest saturated monoalcohol. It is also an important chemical industry basic raw material and clean liquid fuel. It is widely used in organic synthesis, medicine, pesticides, coatings, dyes, automobiles and national defense industries. Methanol is highly toxic, and it can be poisoned by accidental drinking or long-term exposure. Therefore, the relevant national standards have made corresponding regulations on the content of methanol in the air and the concentration of methanol emissions from pollution sources. Corresponding methanol monitoring methods include HJ/T 33-1999 and "Air and Waste Gas Monitoring and Analysis Methods (Fourth Edition Supplementary Edition)" [Gas Chromatography and Spectrophotometry.
