摘　　要：对变色酸光度法测定空气中甲醇的方法进行了改进，在比色波长、显色时间和试剂用量等方面均作了重新选定，使精密度和准确度都有所提高，与气相色谱法比较，分析结果一致。The paper detailed the modification for the determination of methanol in air with chromotropic acid spectrophotometry. The wavelength,time of color developing and reagent amount have been reselected,with the increasing of accuracy and precision. The results are the same to that from gas chromatography.
