Antibiotics have been considered as emerging pollutants due to their continuous input and persistence in the aquatic ecosystem even at very low concentrations. therefore, a wide range of chemical and physical methodologies have been developed to treat antibiotic wastewater such as chemical oxidation, biodegradation, adsorption, liquid extraction and membrane techniques. among these methods, the adsorption process is regarded as a promising method for the removal of micropollutants because of its simple design, low-cost, high efficiency, and less production of toxic intermediates. so, it is of great importance to develop new types of efficient adsorbents. graphene, a new two-dimensional carbon nanomaterial, has been continuously attracting significant research interests as a high-performance adsorbent because of its theoretical large specific surface area. using graphene as a building block and then integrating it into a desired macroscopic three-dimensional (3d) materials, is an efficient strategy which have been proposed.


In this study we used a simple and cost-effective one-pot approach for the preparation of 3d graphene framework.


The characteristic properties of synthesized framework were obtained using scanning electron microscopy and x-ray diffraction. furthermore, a plasma treatment as a clean and green technique was used for the introduction of controlled levels of functionalities onto the surface without the need for wet chemical steps. fourier-transform infrared spectroscopy was performed to ensure introducing functionalities on the surface of graphing framework.


The modified porous graphene framework was used as an adsorbent material for removing antibiotics from aqueous solutions.
