▎ 摘　　要

NOVELTY - A potassium dichromate graphene quantum dots detecting method involves preparing standard solution of potassium dichromate with graphene quantum dot solution, and drawing linear relationship from the fluorescence intensity and concentration of solution from fluorescent spectrum followed by detecting fluorescent intensity of potassium dichromate solution based on standard solution and comparing results with linear relationship. USE - Method for detecting graphene quantum dots of potassium dichromate. ADVANTAGE - The method enables detecting the graphene quantum dots of potassium dichromate with high sensitivity and selectivity in a simple and rapid manner.
