Abstract

The invention discloses an electrochemiluminescence method for detecting graphene oxide. First, PBS buffer solution is added to the electrochemiluminescence cell, and then luminol solution is injected into the solution to obtain a very strong luminol ECL intensity. . Finally, when different concentrations of GO were added to PBS buffer solution containing luminol, different degrees of quenching of luminol ECL were obtained. Based on the inhibitory effect of GO on the ECL of luminol, the ECL signal of luminol was reduced; then it was used for simple, rapid and sensitive detection of GO. In the concentration range of 0.08-800 μg / mL, the logarithm of GO concentration and the intensity value of △IECL showed a good linear relationship, and the detection limit could reach 0.0267 μg / mL. In addition, the sample required by this method is easy to synthesize, the detection is simple, the time is short, and the sensitivity is high. It is expected to be applied to the detection and analysis of GO in actual samples.

Description

technical field

[0001] The invention relates to an electrochemiluminescent method for detecting graphene oxide. The method has the characteristics of fast, simple and sensitive, and belongs to the technical field of electrochemical detection. Background technique

[0002] Due to the continuous production of graphene and the massive use of graphene and graphene-family nanomaterials, there is a need to assess its impact on the environment, ecosystem health, and human life. Graphene oxide (GO) nanoparticles can be discharged into the environment through the atmosphere and waste materials generated in production and research and development. Nanoparticles in the environment can contaminate soil surfaces and groundwater and it can also bind to organic organisms. However, detection methods for graphene oxide such as fluorescence, chromatography, etc. have been developed. Due to the high cost of these techniques, long processing time, and the need for technical skills and complex ...
