▎ 摘　　要

NOVELTY - The method involves drawing a standard absorbency and manganese content relation image curve. Absorbance of a sample is measured. Manganese content is determined according to the absorbance of the sample and the standard absorbency and manganese content relation image curve. Concentration of standard manganese solution is about 3.00 mL. Wavelength of a spectrophotometer is about 530 nm. Standard manganese content vertical coordinate curve is drawn. The sample is placed in a quartz crucible. USE - Graphene oxide and manganese content measuring method. ADVANTAGE - The method enables realizing graphene oxide and manganese content measuring process in a simple and easy manner with high manganese content detection precision and satisfying user requirements. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating relationship between graphene oxide and manganese content measuring characteristics.
