“…Cr(VI) adsorption onto CB can also be verified by different peak alterations and the above results find similarities in the work of other researchers. 30,32,50 X-ray powder diffraction was used to investigate the crystal structure (XRD), and the hump at 25, 2y in Fig. 2(b), along the adsorption line denotes the influence of Cr(VI) adsorption molecules on carbonised biochar.…”

“…27 Adsorption is the easiest and least expensive method to employ, and it can increase effectiveness and be useful for metal concentrations at lower levels. 28 Activated carbon was previously used alone or with certain changes, 29 but now many researchers have focused on biochar adsorbents such as Argemone Mexicana for Zn(II), 30 peanut shell biochar, 31 and sagwan sawdust-derived biochar, 32 and others [33][34][35] with excellent results.…”

“…The main product at the end of the process is pyrolyzed solid biomass. In terms of materials, biochar produced from waste biomass has been found to exhibit great adsorbent potential, as also it enables waste recycling 3‐10 . Therefore, organic fertilizers, sewage sludge and agricultural wastes can be used as feedstocks for biochar production.…”

BACKGROUNDThermochemical conversion methods are essential processes that are frequently used in the production of biochar and affect the properties of biochar. In this study, 2‐naphthol orange was removed from syntethic wastewater using biochar adsorbents produced from pelletized furniture sawdust by thermochemical techniques (torrefaction, pyrolysis, and gasification) at various durations (0.5–5 h) and temperatures (200–900°C).RESULTSThe adsorbent produced via torrefaction process at 200°C and in 1 hour exhibited the best removal performance. For furniture waste biochar (FWB), the optimum conditions for 2‐naphthol orange soption were found to be an initial concentration of 35 mg/L, a pH of 2.0, a contact duration of 2 hours, an agitation speed of 200 rpm, a temperature of 30°C, 1.0 g/L of biochar, and a biochar size of 50 mesh. The Langmuir isotherm and Pseudo‐second order models showed the highest coefficient of determination R2 (R2 = 0.9947 and 0.9978, respectively). The terms of qm (mg/g) and KL were found to be 230.45 and 0.28, respectively from Langmuir isotherm. Conversely, the terms of qe (mg/g) and k2 (g/mg.min) were found to be 29.27 and 0.00486, respectively from Pseudo‐second order model. According to the long‐stability experiment, the selected adsorbent of 200‐1 (biochar from torrefacation) remained more stable after 10 cycles of adsorption.CONCLUSIONIt was found that the torrefaction process provides significant advantages due to the removal efficiencies of 2‐naphthol orange dye and the fact that biochar production is easier and more economical at low temperature values.This article is protected by copyright.

“…Biochar is extensively utilized for heavy metals adsorption (Amin and Chetpattananondh, 2019;Deng et al, 2020;Kumar et al, 2021). However, its limited adsorption capacity and challenging separation from water are two significant impediments to its practical application as material for aqueous heavy metals removal.…”

Hexavalent chromium Cr(VI) causes serious damage to human health. In this study, food waste (FW) was used as raw material to prepare the food waste-derived biochar (FWB), which was further modified using Ce and Fe 2+ /Fe 3+ co-precipitation to obtain Ce dopped magnetic waste-derived biochar (Ce/Fe3O4/FWB ) material for the efficient Cr(VI) adsorption. The morphology, structure, and characteristics of Ce/Fe3O4/FWB composite were thoroughly investigated, and its Cr(VI) uptake behavior was explored. Ce/Fe3O4/FWB showed the best Cr(VI) adsorption of 20.4 mg/g at pH 2.Additionally, the adsorption suited the pseudo-second-order kinetic equation and the Langmuir equation, and the intra-particle diffusion the main step limited the Cr(VI) adsorption by Ce/Fe3O4/FWB. The thermodynamic investigation discovered that the adsorption owned a spontaneous and endothermic nature. With increasing concentrations of Cl -, SO4 2and PO4 3-, the Cr(VI) uptake was weakened in the sequence of Cl -＜SO4 2-＜PO4 3-.Adsorbent preparation for Cr(VI) removal utilizing FW as a raw material is a sustainable and environmentally beneficial technology for FW reclamation and Cr(VI)-bearing wastewater treatment.
