▎ 摘  要

NOVELTY - The method involves adsorbing the uses graphene material to absorb pollution source exhaust gas containing benzene series. The thermal desorption on the graphene material is performed after adsorption by thermal desorption. A mass spectrometry detection analysis is performed by analyzing and collecting the desorbed gas. The graphene material is filled in the adsorption tube and supported and fixed by glass wool and a sieve plate. The mesh number of the graphene material is 40-50 mesh. The adsorption tube is pumped so that the pressure in the adsorption tube is not greater than 5KPa after the graphene material is filled into the adsorption tube. USE - Sampling detection method based on material graphene benzene series material. ADVANTAGE - The method uses the material graphene to absorb the pollution source waste gas containing benzene to absorb, and has good absorbing ability, and the price is relatively cheap, so the analysis precision of each component in the benzene series material in the waste gas is improved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the sampling detection method based on material graphene benzene series material.
