“…The FTIR spectra prefigured the roles of functional groups in the sorption of MO by the biochar (Aichour et al, 2022). The interaction of MO molecules with the lone pair e − of N and P atoms available in –CN and P=O bonds in the activated biochar may result in higher adsorption than raw biochar.…”

“…Both raw and activated biochar demonstrated two‐phase sorption, e.g., high sorption initial phase and low sorption later phase, which is identical to other reported biochars for the sequestration of different dye and metal species (Chu et al, 2020; Kwak et al, 2019; Zeghioud et al, 2022). In the initial phase, the biochar surface has abundant active sites (Liu et al, 2022), promoting the interaction of pollutants molecules with the sorption sites (Roy et al, 2022); these sites become saturated with time, leading to decreasing sorption of MO molecules (Aichour et al, 2022).…”

“…About six times greater adsorption capacity was achieved for activated biochar compared to the raw biochar, which is expected as the activated biochar has a higher surface area, porous structure, intense functional groups, and stability than raw biochar. The diffusion of MO in the tunnel-like canals in the activated biochar surface may promote the eradication of dye molecules (Aichour et al, 2022). Scientists have reported several mechanisms for organic and inorganic pollutant sorption onto natural and synthetic sorbents (Kubra et al, 2021b).…”

Biochar is a promising engineering material to sequestrate organic pollutants from wastewater. In the current study, several surface-modified Moringa (M.) oleifera leaf biochars were prepared and utilized for the sorption of methyl orange (MO) dye from an aqueous solution. Raw biochar was produced by the carbonization of M. oleifera leaves at 350°C in a muffle furnace for 2 h. The surface-modified M. oleifera biochars were prepared at 400°C, 500°C, and 600°C using phosphoric acid (H 3 PO 4 ) at different combinations to improve the biochar pore structure, surface functional groups, and biochar stability. The highest surface area (267.15 ± 42.40 m 2 /g) of the modified biochar was achieved at 500°C with H 3 PO 4 to raw biochar ratio of 1.5. Surface morphological results revealed the formation of pores, troughs, and channels with the increasing activation temperature. The carbon (C) content (wt%) was maximum (79.61%) for activated biochar at 500°C. The presence of enhanced functional groups, e.g., hydroxyl, aliphatic carbon-hydrogen, carbonyl, ester, and phenol structures in surface-modified biochars was observed from FT-IR results. The Langmuir isotherm model was fitted to better describe the adsorption phenomenon for both surface-modified biochars and raw biochar compared to the Freundlich isotherm model. The highest adsorption capacity was

“…Therefore it can to be expected that the process is reversible and not confined to the formation of a single adsorbent layer (Nanta et al, 2018), (Deng et al, 2021). The large value of R 2 calculated from the Temkin model shows that the electrostatic interactions play an important role in the sorption process (Aichour et al, 2022). The sorption process of Cd(II) ions is temperature-dependent as shown by the data in Fig .…”

To develop the sorption efficiency of heavy metals: Cd(II), Co(II), Zn(II) and Pb(II) ions the biochar was modified by chitosan, FeSO4 and NaBH4. The morphology, physical structure and chemical composition of the biochar based sorbents were characterized by the scanning electron miscroscopy method, N2 adsorption and desorption isotherms, X-ray diffractometry as well as the Fourier transform infrared spectroscopywith the attenuated total reflectance analyses. The research of M(II) ions sorption was carried out as a function of pH (2-6), interaction time (0-360 minutes) and temperature (293, 313, 333 K). The maximum sorption was obtained by the ChBC for Zn(II) ions -19.23 mg/g and for MBC-Pb(II) -19.11 mg/g. Different kinetic models as well as both isotherm and thermodynamic equations were used the sorption data modelling. For Cd(II), Co(II) and Zn(II) ions the nonlinear regression of the Elovich equation gave the best fit for the experimental data. On the other hand, for Pb(II) ions, the nonlinear forms of pseudo first order and pseudo second order show a better match. The value of the correlation coefficient >0.960 determined from the Freundlich isotherm model is the highest suggesting a good fit to the experimental data. The thermodynamic parameters: ∆G°, ∆H° and ∆S° were listed and indicated that the process is spontaneous and endothermic in nature. The desorption efficiency was determined with the use of nitric, hydrochloric and sulfuric acids and the largest desorption yield for Pb(II)-ChBC equal 99.5 % was gained applying HNO3.

Heavy metals and dyes cause serious harm for water environment, geopolymer materials with the large pores and specific surface area, and easy modification of pore surface have received extensive attention in wastewater treatment. Herein, using loess‐clay (LC) as natural mineral materials, we developed an eco‐friendly geopolymer of loess‐clay (GpLC) with excellent adsorption properties and promotion plant growth was prepared by alkali excitement. Its morphology and structure were exhibited by scanning electron microscopy, Fourier transform infrared spectroscopy, XRD, and Brunauer–Emmett–Teller. Moreover, its adsorption property for removing metal ions and different dyes was measured, and the adsorption kinetics and thermodynamics were investigated. GpLC presented excellent adsorption ability for Pb2+, which the removal rate got to 98.7 %. It had the universality of removing organic pollutants, and the removal rate reached to 98.0 %. It was dominated chemisorption and single‐layer adsorption, which GpLC conformed to quasi‐second‐order adsorption kinetics, and being more consistent with Langmuir isothermal model. Furthermore, it was found that GpLC could promote growth of crops as it contain P and K element with essential element of plants. In summary, it provides insights and strategy for developing a kind of eco‐friendly functional materials with strong adsorption capacity and promoting plant growth, and it is an effective method for reusing loess resources.
