“…As for Ni, the peaks at 856.1 and 873.7 eV corresponded to the peaks of Ni 2p 3/2 and Ni 2p 1/2 , which were attributed to Ni(OH) 2 [ 67 , 79 ]. The peaks that appeared at 860.2 eV belonged to NiO(OH) and 879.1 eV peak was attributed to the corresponding satellite peak of Ni 2p [ 67 , 80 ], indicating that precipitation was an important mechanism of Ni adsorption on Mn 3 O 4 –AL.…”

Argillaceous limestone (AL) is comprised of carbonate minerals and clay minerals and is widely distributed throughout the Earth’s crust. However, owing to its low surface area and poorly active sites, AL has been largely neglected. Herein, manganic manganous oxide (Mn3O4) was used to modify AL by an in-situ deposition strategy through manganese chloride and alkali stepwise treatment to improve the surface area of AL and enable its utilization as an efficient adsorbent for heavy metals removal. The surface area and cation exchange capacity (CEC) were enhanced from 3.49 to 24.5 m2/g and 5.87 to 31.5 cmoL(+)/kg with modification, respectively. The maximum adsorption capacities of lead (Pb2+), copper (Cu2+), and nickel (Ni2+) ions on Mn3O4-modified argillaceous limestone (Mn3O4–AL) in mono-metal systems were 148.73, 41.30, and 60.87 mg/g, respectively. In addition, the adsorption selectivity in multi-metal systems was Pb2+ > Cu2+ > Ni2+ in order. The adsorption process conforms to the pseudo-second-order model. In the multi-metal system, the adsorption reaches equilibrium at about 360 min. The adsorption mechanisms may involve ion exchange, precipitation, electrostatic interaction, and complexation by hydroxyl groups. These results demonstrate that Mn3O4 modification realized argillaceous limestone resourcization as an ideal adsorbent. Mn3O4-modified argillaceous limestone was promising for heavy metal-polluted water and soil treatment.

“…The second stage was conducive to intra-particle diffusion, with hydroquinone gradually entering the internal biochar surface through the pore structure. The last stage was the equilibrium state of adsorption, and the intraparticle diffusion rate decreased as the diffusion resistance increased (Sun et al 2022;Xia et al 2022). The tted curve for all three stages was not through the origin, indicating that the adsorption of hydroquinone was in uenced by various adsorption processes (Table S3).…”

The adsorption capacity of pristine biochar for hydroquinone solutions was limited, while modified biochar could significantly enhance adsorption performance. Modified biochar BCNP-Fe, BCHNP-Fe, and BCP-Fe were produced by mixing corn stover with the solutions of ammonium phosphate and ferrous sulfate, the solutions of diammonium hydrogen phosphate and ferrous sulfate, and the solutions of phosphoric acid and ferrous sulfate for removing hydroquinone solutions. The maximum adsorption capacities of BCNP-Fe, BCHNP-Fe, and BCP-Fe were 154.321, 203.666, and 142.045 mg/g, respectively, which were 1.09, 1.44 and 1.00 folds of BC. The adsorption kinetics and isotherm studies of the modified biochars probably involved physical and chemical adsorption. Thermodynamic studies further suggested that higher temperature was favorable for adsorption, and adsorption exhibited endothermic behavior. The adsorption mechanism of hydroquinone on BCNP-Fe, BCHNP-Fe, and BCP-Fe included the π-π interactions, electron donor-acceptor, hydrogen bonding, pore filling, hydrophilicity, and surface complexation. BCNP-Fe, BCHNP-Fe, and BCP-Fe were promising adsorbents for removing hydroquinone solutions as well as promising candidates for water treatment due to their simple preparation and high adsorption capacity.
