Graphene quantum dots (GQDs) are small fluorescent nanoparticles with unique properties that make them attractive tools for research in various scientific fields. Graphene has attracted increasing attention among the scientific community ever since it was isolated as a single layer of material from highly oriented pyrolytic graphite (HOPG) in 2004 by Novoselov and Geim using the “Scotch-tape method”. GQDs, as defined, are a kind of 0D material with characteristics derived from both graphene and carbon dots swhich can be regarded as incredibly small pieces of graphene. Suitable analytical techniques are needed for the quality control. Chemiluminescence (CL) detection has become quite a useful tool in the last years due to its simplicity, low cost and high sensitivity. Moreover, no external light source is needed. CL is often described as a dark-field technique: the absence of strong background light level reduces the background signal and leads to improved detection limits. Due to these advantages, CL methods have been widely applied to analysis in recent years. Surfactants are one of the major components (10-18%) of detergent and household cleaning products and are used in high volumes. Several types surfactants of are commonly found in natural waters and consequently, their impact on the environment has been, and continues to be, discussed in the U.S.A., Western Europe and Japan. Then, the prepared GQDs. It was found that GQDs in the presence of cetyltrimethylammonium bromide (CTMAB) and in alkaline medium led to emission of light. In order to obtain highest light emission, the concentrations of reactants involved in the CL reaction were optimized. After optimization, our preliminary tests revealed that Triton X100 could inhibit the CL reaction of GQDs. The inhibitory effect of triton X 100 was linearly proportional with concentration of triton x100 in the range of 1.2×10-3 – 1.5×10-2 mol/L. The limit of detection of CL method and its relative standard deviation we
