▎ 摘　　要

NOVELTY - The method involves establishing a linear relationship based on multi part standard solution. A graphite alkene quantum point is fixed with a fluorescent probe. The linear relationship is established between a fluorescence intensity value and a trivalent iron concentration value of a graphite alkene quantum point. The fluorescence intensity value is calculated based on ferric ion solution. The graphite alkene quantum point solution is added with the ferric ion solution. USE - Graphene quantum point ferric ion fluorescence intensity detecting method. ADVANTAGE - The method enables providing simple operation, and ensures rapid detection effect, high sensitivity and wide application range. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating a graphene quantum point ferric ion fluorescence intensity detecting method.'(Drawing includes non-English language text)'
