The development of high-efficient adsorbents for the treatment of antibiotics from contaminated water has been of great concern.This work introduced an alco-hol-solvent mediated strategy to increase the specific sur-face area (SSA) and porosity of hexagonal boron nitride nanosheets (BNNSs) for improving tetracycline (TC)removal efficiency.The BNNSs synthesized with the mediation of n-propanol solvent (BN-P) exhibited the lar-gest pore volume and relatively high SSA (increased by 34％ and 64％,respectively,compared with that synthe-sized under the mediation of water) in its structure,which in turn facilitated the mass transfer of TC molecules onto BN-P framework.The remarkable adsorption performance of BN-P,with 20％ increase in equilibrium adsorption capacity and Langmuir maximum adsorption capacity of 556 mg·g-1,was achieved for capturing TC within just 3 h,which is mainly through π-π interaction and electro-static force.Pseudo-second kinetics equation can well illustrate the adsorption process,while Freundlich and Langmuir isotherm models fitted the equilibrium data well.Thermodynamics study demonstrated a spontaneous exothermal adsorption process.Furthermore,the strong environmental suitability and notable recycling perfor-mance of BN-P revealed its good application prospect in removing antibiotic TC from wastewater.
