▎ 摘  要

NOVELTY - The method involves obtaining a methylene blue standard solution working curve for determining different concentrations of a methylene blue solution. Solid-liquid separation is performed after finishing absorbing operation. A filtrate is collected for testing absorbance of the solution. A specific surface area is calculated according to an absorbency test. Concentration of the methylene blue standard solution working curve is determined. Equilibrium adsorption amount is counted. Concentration of the filtrate is determined according to Langmuir adsorption equation. USE - Graphene material specific surface area measuring method. ADVANTAGE - The method enables effectively utilization of graphene sheet between stack and agglomerated so as to realize high graphene material specific surface area measurement accuracy. The method enables realizing better operation convenience and low testing cost. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating a graphene material specific surface area measuring method. '(Drawing includes non-English language text)'
