NOVELTY - The method involves igniting and placing certain mass of sandalwood in a first sealed box body. An air pump is turned on to pump after the sandalwood is burned out. The electric fan in the second sealed box body is turned on. The concentration of particulate matter 2.5 (PM2.5) is measured in a first sample measuring point (1) and a second sample measuring point (2) after the electric fan is disturbed for a period of time. The adsorption efficiency is calculated. USE - Graphene oxide/polyvinylidene fluoride composite film adsorption PM2.5 test method. ADVANTAGE - The method enables achieving excellent PM2.5 absorption performance of the graphene oxide/polyvinylidene fluoride composite film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene oxide/polyvinylidene fluoride composite film adsorption PM2.5 testing method.
