Graphene quantum dots and the resonance light scattering technique for trace analysis of phenol in different water samples

A high selective and sensitive method for trace detection of phenol in waste water samples was developed by using the resonance light scattering (RLS) technique. The method involves the use of graphene quantum dots (GQDs) and the phenol was catalyzed by horseradish peroxidase (HRP) and H2O2 to produce an intermediate of quinone, which was combined with GQDs to enhance the RLS intensity.
