NOVELTY - The method involves burning corundum crucible. The crucible is cooled. Quantity of aqueous solution is added into the corundum crucible. Ash is produced by heating the crucible. Solution in the crucible is transferred to a volumetric flask. A crucible inner wall is washed by using pure water. Cleaning solution is transferred to the volumetric flask. Pure water is added to constant volume. The solution is shacked based on atomic absorption spectrophotometer of operation procedure. Standard solution and sample solution are tested. Content of a metal element is calculated from test result. USE - Method for detecting metal element content in graphene sample. ADVANTAGE - The method enables detecting metal element content in the graphene-like material in a simple and accurate manner and improving high analyzing efficiency.
