摘要: An environmentally benign and efficient hydrothermal reduction method was applied for the preparation of three-dimensional (3D) porous graphene hydrogel (GH) adsorbents. The physicochemical properties GH granules were systematically characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectra Brunauer-Emmett-Teller (BET) method. showed an excellent adsorption capacity (235.6 mg/g) ciprofloxacin via combined interaction mechanisms (e.g. π-π EDA interaction, hydrogen bonding, hydrophobic interaction). Moreover, reducing size hydrogels can significantly accelerate process enhance removal efficiency pollutants from aqueous solution. Water (more than 99 wt%) within played a key role in enhancing performance. GO exhibited adaptability to environmental factors. These findings demonstrate that are promising adsorbents antibiotic solutions.
