A novel composite material, ALBC@nZVI, was synthesized by loading nano zero-valent iron (nZVI) onto activated luffa-derived biochar (ALBC) via in-situ liquid-phase reduction. The ALBC was prepared through pyrolysis of natural porous luffa sponge at 600 ℃, followed by KOH activation at 800 ℃. The composite was characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectrometer, confirming the porous structure of ALBC and uniform dispersion of nZVI on its surface. The Cr(Ⅵ) removal performance was systematically investigated under varying pH values (2-8), adsorbent dosage (0.25-2.0 g·L^-1), and reaction time (0-360 min). Results showed that ALBC@nZVI achieved a maximum adsorption capacity of 95.27 mg·g^-1 and a removal efficiency of 95% at a pH of 2, with an adsorbent dosage of 1.00 g·L^-1 and an initial Cr(Ⅵ) mass concentration of 100 mg·L^-1. The adsorption process followed the Langmuir isotherm and pseudo-second-order kinetics, indicating monolayer chemisorption. X-ray photoelectron spectrometer (XPS) analysis reveals that the removal of Cr(Ⅵ) is synergistically driven by multidimensional mechanisms, including electrostatic attraction, redox reactions, and surface complexation-coprecipitation. The ALBC@nZVI exhibits the advantages of high adsorption performance, strong reducibility, and rapid magnetic separability (The specific saturation magnetization was 23.4 emu·g^-1).
