环境空气和废气 甲醇的测定 变色酸分光光度法

本标准规定了测定环境空气、无组织和固定污染源废气中甲醇的变色酸分光光度法。 本标准适用于山西省境内环境空气和废气中甲醇的测定。 当定容体积为5 mL时，方法检出限为1.45 μg，测定下限为5.80 μg。

此法操作复杂，费时费力，效率低下

Ambient air and waste gas - Determination of methanol - Chromotropic acid spectrophotometry
This standard specifies the chromotropic acid spectrophotometric method for the determination of methanol in ambient air, waste gas from unorganized and fixed pollution sources. This standard applies to the determination of methanol in ambient air and waste gas in Shanxi Province. When the constant volume was 5 mL, the detection limit of the method was 1.45 μg, and the lower limit of determination was 5.80 μg.

​​​​​​​This method is complicated, time-consuming, labor-intensive, and inefficient
