Determination of Methanol and Ethanol in Composite Carbon Source by Gas Chromatography-mass Spectrometry
The methanol and ethanol in the composite carbon source for sewage and wastewater treatment were detected by gas chromatography-mass spectrometry,and a rapid and efficient detection method was established.In the linear range of 15～160 mg/L,the linear coefficient was greater than 0.999,the recovery rate was 95.2％～98.8％,and the relative standard deviation of repeated determination was less than 2％.This method can accurately detect the mass fraction of methanol and ethanol in the composite carbon source.
