英文摘要	Transformation of waste into adsorbent achieves treating waste by waste. Here, 3D graphene with a large specific area was derived from waste leaf and employed for tetracycline removal from the aqueous solution. The influence of pH value on this antibiotic was evaluated, and then the adsorption behavior was studied by the analyses of two kinetics models (pseudo-first-order and pseudo-second-order equations) and two isotherm models (Langmuir and Freundlich). The Langmuir and the pseudo-second-order were best fitted for tetracycline uptake of the waste leaf graphene (WLG). The maximum adsorption capacity of WLG calculated from the Langmuir model was 909.09 mg/g. For the treatment of groundwater, WLG has an effective removal of organic pollutants and heavy metals, which indicates the fascinating potential application in water treatment. The facile preparation routine of graphene with low-cost and nontoxic characters is also resulting in macroscopic shape and excellent adsorption performance of the obtained 3D graphene. The study would offer a new version for the fabrication of graphene with the purpose of waste reclamation, and the obtained functional 3D graphene can be tremendously used in environmental pollution treatment and other areas.
