“…Direct pyrolysis method of the final MAS materials was performed at 700°C to produce B-700 biochar with a heating rate of 10°C/min for 4 hours using a muffle furnace (DAIHAN Scientific) under limited oxygen. The choice of the direct pyrolysis method, along with the specific temperature of 700°C, was based on existing literature [ 10 , 11 ]. This body of research indicates that elevated temperatures facilitate the degradation of organic compounds, leading to the formation of a material consisting primarily of carbon.…”

Biochar has shown large potential in water treatment because of its low cost, good textural properties, and high reusability. In this study, two porous biochars were developed from the Melia azedarach seeds via direct pyrolysis process (B-700) and through hydrothermal carbonization followed with pyrolysis (HB-700). They were characterized by morphology, structural characteristics, and surface features and used to adsorb the crystal violet (CV) dye in water environment. Results of the isotherm approaches demonstrated that the removal capacity of these biochars reached 119.4 mg/g for B-700, and 209 mg/g for HB-700 (at 45°C). Also, the Avrami model best fitted the kinetic data. The electrostatic attraction was regarded as one of the adsorptions mechanisms of CV dye. The regeneration tests reveal that both B-700 and HB-700 are good reusable adsorbents. Finally, findings of the study showed that the hydrothermal carbonization method that precede the pyrolysis process can improve significantly the adsorption capacity of the produced biochar.

“…For the reason, several techniques have emerged for the modification of OP, including chemical modification [9], carbonization [10], and activated carbon preparation [11]. Researchers have found that carbonization and thermal activation contribute to improve the stability and adsorption effect of this biomaterial, which is related to its growing specific surface area, abundant mineral content, and pore structure [12][13][14]. Interestingly, the carbonization temperature at which biochar is prepared plays a crucial role in its quality [15].…”

In this work, orange peel (OP) was used as raw material to produce biochar. The effect of oxygen-limited carbonization temperature (200, 400, and 600°C) on the physicochemical properties and adsorption behavior of orange peel biochar (OPB) toward La(III) and Y(III) in aqueous media was studied. The prepared OPB samples were characterized by SEM, FTIR, and XRD. The experimental results exhibited effective removal of La(III) and Y(III) from aqueous solution by OPB. The carbonization promoted the pore development, and the adsorption process occurred rapidly. The main chemisorption of La(III) and Y(III) on OPB was analyzed by the Langmuir and pseudo-second-order kinetic model, and the participations of electrostatic attraction, exchange, and hydroxyl and carboxyl complexation in OPB were confirmed. The Langmuir maximum capacity of 55.57 mg/g and 31.49 mg/g was obtained at the optimum pH range of 4~6 and the OPB dosage of 1 g/L and 2 g/L for La(III) and Y(III). The efficient orange peel biochar with high adsorption performance can be obtained by considering suitable carbonization temperature.
