Abstract
The hydrothermal method as the eco-friendly environmental method was used in this study to prepare a high efficient nanocomposite adsorbent based on the biochar (BC) derived from Eriobotrya japonica leaves and magnesium oxide nanoparticles (MgO NPs). The prepared materials were characterized using FTIR, BET, SEM-EDX, TEM, and XRD. The adsorption of tartrazine (TZ) on BC, MgO NPs, and BC@MgO NPs was better described by the kinetic pseudo 2nd order model and followed the Langmuir isotherm model. The maximum uptake (Qm) was 643.50 mg g−1 at 25 ± 1 °C for BC@MgO NPs. The calculated thermodynamic suggests that the TZ dye adsorption on BC, MgO NPs, and BC@MgO NPs was spontaneous and endothermic. The TZ-loaded BC@MgO NPs was recycled and regenerated in six cycles with better adsorption efficiency. Under conditions optimal (C0 = 50 mg L−1, BC@MgO NPs dose = 0.4 g L−1, and pH = 4), the TZ removal was 99.51% with Box–Behnken design (BBD)-based optimization. The synthesis of BC@MgO NPs showed great potential adsorbent for dye removal from wastewaters.
