大气中甲醇测定方法的研究

Study on the method of determining methanol in the air

用水吸收大气中的甲醇,在酸性溶液中用高锰酸钾把甲醇氧化成甲醛,再与变色酸作用生成紫色化合物,进行比色测定。

Methanol in the air was adsorbed with water and oxidized to form formaldehyde solution by potassium permanganate under the condition of acid solution, then formaldehyde solution reacted with chromotropic acid to form purple compound, which can be determined using colorimetry.
