“…This may be attributed to the presumption that all the single-bond hydroxyl-containing species in this range were released as volatiles during pyrolysis. Similar results were reported by Savitri et al [58] on biochar produced from oil palm empty fruit bunches for Mn 2+ removal from aqueous wastewater. The presence of functional groups makes the samples have more affinity with or be chemically more reactive to other species in their surroundings [8].…”

“…Four distinct peaks were observed, with peak centres of 1326 cm −1 , 1624 cm −1 (, 2326 cm −1 and 2931 cm −1 . The peak at 1326 cm −1 is attributed to the OH in-plane bending, which corresponds to the presence of a tertiary alcohol or phenol [57]; the 1624 cm −1 peak indicates the presence of C=C stretching, which indicates the presence of lignin in the biochar [58]; 2326 cm −1 indicates the presence of groups with triple bond structures such as C ≡ N (nitriles) and C ≡ C (alkynes) groups on biochar [59]; and 2931 cm −1 is assigned to the hydrogen-bonded OH groups of dimeric COOH groups [60].…”

The valorisation of waste from rose-based industrial products produces value-added substances and paves the way for advanced composites. The rose waste generated from the essential oil industry of the Taif rose (Rosa damascena trigintipetala Dieck) is significant, and its management or disposal is a source of concern. In this study, it was valorised to produce a value-added nanomaterial. The synthesis of biochar nanoparticles via high-energy ball milling has gained tremendous research interest in recent times because of its low cost and eco-friendliness. Ball milling is a solvent-free technology with strong potential for waste volatilisation and eco-sustainability through the production of engineered biochar nanoparticles. Different biochar samples were produced and characterised to harness the synergistic combination of biochar production and ball milling. They were prepared at a constant pyrolysis temperature of 300oC by varying the pyrolysis times for 2 h, 5 h, and 10 h. The characterisation results showed that pyrolysis confirms a high content of carbon, minerals, graphitic structure, novel morphology and chemical characteristics attached to the biochar surface controlled by different pyrolysis durations. These properties were further enhanced by ball milling for 10 h. The results showed that ball milling enhanced the porosity, surface area, surface functional groups, visible light absorption, crystallinity, and carbon content, and these were accompanied by a reduction in the particle size and mineral impurities. The engineered biochar can be an important tool, with promising potential in novel composites for water purification and energy harvesting.

“…Table 5 shows a comparative study of the absorption of Fe 2+ , Mn 2+ , Cu 2+ , and Zn 2+ from wastewater by various adsorbent materials. According to the literature review [55][56][57][58][59][60][61][62][63][64][65], biochar derived from various materials has a wide range of Fe 2+ , Mn 2+ , Cu 2+ , and Zn 2+ adsorption limits, and RSBC has a certain degree of comparability. In consideration of the industrial application and subsequent soil application, RSBC has an advantage that other adsorbents do not have.…”

Copyrolysis biochar derived from rape straw (RSBC) was prepared through oxygen-limited pyrolysis at 500 °C and utilized to investigate its adsorption capability for single and complex trace elements (Fe2+, Mn2+, Cu2+, and Zn2+) in contaminated solutions. The microstructures, functional groups, and adsorption behaviors of RSBC were determined through scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and batch adsorption experiments, respectively. From these, the single/complex adsorption results showed that the adsorption capacity of RSBC for Fe2+, Mn2+, Cu2+, and Zn2+ was 32.21/23.78, 8.95/3.41, 28.12/7.19, and 13.77/4.92 mg/g, respectively. The Langmuir isotherm model fit better than that of Freundlich in the mixed adsorption system, while the pseudo-second-order kinetic model was the most suitable for single adsorption. Thermodynamic adsorption analysis revealed that the removal rate of the four ions by RSBC was 22.14%, 8.95%, 18.75%, and 13.77%, respectively. Moreover, the adsorption mechanism was primarily chemical adsorption, including ion exchange, precipitation, and complexation, because of the binding effects of aromatic structures and polar groups. Additionally, biochar, with its porous structure and high ash content also provided favorable conditions for adsorption of those ions. Through this simple procedure, this work provides a potential strategy to produce biochar with a high adsorption capacity to remediate trace elements in contaminated solutions.
