NOVELTY - Detecting graphene composition slurry comprises e.g. drawing a working curve by mixing anon-graphene carbon material slurry and pure graphene slurry in different to obtain series of composition slurry with different graphene ratios as standard samples for sample configuration, using laser particle size instrument for particle size distribution test composition slurry to obtain the particle size of these sample-volume distribution curve, using two pure and graphene-type carbon material slurry sample of the particle size distribution peak position as reference, and comparing and determining each particle size distribution peaks corresponding to compound slurry in graphene and non-graphite alkene carbon material, where the particle size of in-volume distribution curve are: abscissa particle size value taking the logarithm, ordinate unchanged to obtain the particle size distribution spectrum after conversion, and calculating the actual unknown sample graphene content of the total carbon. USE - The method is useful for detecting graphene composition slurry. ADVANTAGE - The method: is able to analyze the graphene content in graphene composition slurry by simply, rapidly and qualitatively and quantitatively. DETAILED DESCRIPTION - Detecting graphene composition slurry comprises (i) (i-a) drawing a working different graphene ratios as standard samples, (i-b) using laser particle size instrument for particle size distribution test compound slurry in step a to obtain the particle size of these sample-volume distribution curve a sample configuration including a non-graphene carbon material slurry and a pure graphene slurry are mixed in different to obtain a series of composition slurry with ion curve, (i-c) using two pure and graphene-type carbon material slurry sample of the particle size distribution peak position as reference, and comparing and determining each particle size distribution peaks corresponding to compound slurry in graphene and non-graphite alkene carbon material, the particle size of step b in-volume distribution curve are: abscissa particle size value taking the logarithm, ordinate unchanged to obtain the particle size distribution spectrum after conversion, respectively for peak area of the graphene portion and non-graphene part the particle size distribution spectrum conversion after-fitting, ratio to graphene abscissa, the ratio of the total carbon material is graphene particle size distribution peak area accounting for total peak area of carbon material as the longitudinal coordinate drawing curve, fitting relation equation; and (ii) processing the actual unknown sample test using a laser particle size instrument testing the actual ratio sample of particle size distribution, the particle size distribution peak position determines the slurry types: graphene slurry, non-graphene slurry or both compound slurry, when determined to be compound slurry, the processing according to the method in step c the particle size distribution spectrum, calculating the graphene and non-graphite alkene carbon material fitting each corresponding particle size distribution peak area, the ratio of the ratio sample graphene particle size distribution peak area accounting for total peak area of carbon material is substituted into the working curve in step (c), and calculating the actual unknown sample graphene proportion of the total carbon.
