Abstract The good aqueous suspensions of amphiphilic aminated carbon black nanoparticles (CB-EDA) are prepared via situ grafted methodby industrial carbon black for treating 10.0wt% crude oil in water emulsions (pH=8.9). The structure and morphology characterization of CB-EDA were explored by Fourier transform infrared spectroscopy (IR), X-ray photoelectron spectroscopy (XPS), Atomic force microscopy (AFM), and high-resolution transmission electron microscopy (TEM). Encouragingly, the demulsification tests indicated that the residual oil in separated water samples was as low as 53.45 mg/L, corresponding to a demulsification effect of over 99.90% at optimum dosage. Besides, the CB-EDA, graphene oxide (GO), reduced graphene oxide (rGO), and hydroxylated carbon black (CB-PVA) for detachment oil from the crude oil-in-water emulsion under alkaline conditions are studied. The zeta potential measurement and mechanism analysis results revealed that CB-EDA has better demulsification efficiency and universality than other nanocarbon-based demulsifiers at ambient temperature. As an amphiphilic nanocarbon-based material, the CB-EDA prefer to migrate to the oil/water interface after add into emulsions adding once CB-EDA is reached at the oil/water interface which can displace the emulsified molecules of the emulsion by strong π-π/n-π interaction. More importantly, the zeta potentials are CB-EDA is positive, which can compress double electric layer of dispersed oil droplets to promote emulsified oil droplets accumulation. In the current work, we overcame the disadvantages of the nanocarbon-based demulsifiers, effectively improved their efficiency and universality, and developed a promising CB-EDA demulsifier for the separation of O/W emulsion.
