| 英文摘要 | akaganeite (beta-feooh) nanoparticles were successfully anchored on the surface of porous sea buckthorn biocarbon (sbc) via a simple low-temperature hydrothermal process without use of surfactants or external forces. the sbc@beta-feooh composite was characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), and energy dispersive spectrometry (eds). on the basis of characterization methods, a possible mechanism of formation of the sbc@beta-feooh composite was discussed. the sbc@beta-feooh composite was used in fixed-bed columns for the effective removal of doxycycline (dc) from an aqueous solution, by the synergistic effect of adsorption and subsequent fenton-like oxidation reaction, which oxidized the sorbed dc. the effects of inlet dc concentration (22-32 mg/l) feed flow rate (1-3 ml/min) sbc@beta-feooh bed depth (0.7-1.5 cm) and ph (2-11) on the adsorption breakthrough profiles were investigated. the adsorption process was controlled by the ionic speciation of the adsorbate dc and the available binding sites of sbc@beta-feooh. it was simulated by the thomas and yoon-nelson models under different conditions. the bed of sbc@beta-feooh saturated with dc was readily regenerated, in situ, by a heterogeneous fenton-like oxidation reaction. the synergistic effect resulting from the biosorption nature of sbc and the catalytic oxidation properties of the supported beta-feooh nanoparticles results in a new promising composite material for water treatment and purification.
