“…The findings of this study exhibit that FeCl 3 -modified adsorbent has potential applications as an efficient, recyclable composite for antibiotic elimination from wastewater (Sun et al, 2022). Liang et al (2022) found a higher sorption capacity (38.70 mg g −1 ) of CaCl 2 /FeCl 2 -modified BC for norfloxacin than pristine BC. Furthermore, the adsorption mechanism of norfloxacin on composite was thermodynamically spontaneous (Liang et al, 2022).…”

Water contamination by aquatic pollutants (antibiotics, heavy metals, nutrients, and organic pollutants) has become the most serious issue of recent times due to associated human health risks. Biochar (BC) has been deemed an effective and promising green material for the remediation of a wide range of environmental pollutants. Due to its limited properties (small pore size and low surface functionality), pristine BC has encountered bottlenecks in decontamination applications. These limitations can be rectified by modifying the pristine BC into engineered BC via multiple modification methods (physical, chemical, and mechanical), thus improving its decontamination functionalities. Recently, these engineered BCs/BC-based composites or BC composites have gathered pronounced attention for water decontamination due to fewer chemical requirements, high energy efficiency, and pollutant removal capacity. BC-based composites are synthesized by mixing BC with various modifiers, including carbonaceous material, clay minerals, metals, and metal oxides. They considerably modify the physiochemical attributes of BC and increase its adsorption ability against various types of aquatic pollutants. BC-based composites are efficient in eliminating target pollutants. The efficiency and type of a specific mechanism depend on various factors, mainly on the physicochemical characteristics and composition of the BC-based composites and the target pollutants. Among the different engineered BCs, the efficiency of clay-BC composites in removing the antibiotics, dyes, metals, and nutrients was good. This review could help develop a comprehensive understanding of using engineered BCs as effective materials for the remediation of contaminated water. Finally, gaps and challenges in research are identified, and future research needs are proposed.

“…In recent years, the remediation e ciencies based biochar techniques were highly improved through developing new composites to improve interactions and bonding abilities with antibiotic (Patel et al 2022). Liang et al developed a Fe 2 O 3 /biochars composite which had exhibited higher removal e ciency for norfoxacin than original biochar (Liang et al 2022). The study has shown a promising strategy for removing antibiotics from water.…”

Increasing antibiotics pollution is becoming an urgent public health issue. Biochar is a kind of promising solution for antibiotic removal in aqueous environment. However, the adsorption and degradation performance of pristine biochar was limited because of the relatively lower speci c surface. The remediation e ciencies could be highly improved through developing new biochar-based composites which have high interactions and bonding abilities with antibiotic. In this study, a novel magnetic graphoxide/biochar composite (mGO/TBC) was fabricated as an e cient and recyclable persulfate (PS) activator for degradation and removal of sulfonamides (SAs) and quinolones (QNs) antibiotics. Based on the synergism presorption and degradation of graphoxide and biochar, the removal rates of mGO/TBC for sara oxacin hydrochloride, sulfadimethoxine, sulfapyridine, sulfado xine, sulfamonomethoxine, sulfachloropyridazine, enro oxacin, and cipro oxacin were increased above 85%. Quenching experiment and ESR analysis had proved that 1 O 2 , • OH and SO 4•− from mGO/TBC/PS system were the primary oxidation active species to degrade SAs and QNs. Furthermore, the mGO/TBC is easy to be batch produced due to simple synthesis steps. It is a promising substrate for antibiotic bioremediation with good application prospects. HighlightsComparison study on biochars and mGO/TBC was made on multiple SAs and QNs removal.The synergism presorption and degradation can increase removal rate of SAs and QNs from 36.60% to 99.31%.Oxygen ( 1 O 2 ), • OH and SO 4 •− acted as the primary oxidation active species to degrade SAs and QNs.The mGO/TBC could be recycled and easy to be batch produced due to simple synthesis steps.

“…For example, MgO@BC, which is synthesized via straws and MgCl 2 •6H 2 O, reveals a much higher Cd 2+ adsorption capacity (1058.8 mg g − 1 ) compared with the pristine biochar (Wang et al 2021b). Magnetic biochar composites (Fe 2 O 3 /biochar) exhibit a huge potential for rapid and efficient adsorption of antibiotics (Liang et al 2022a). Currently, a number of reviews have systematically summarized the synthesis, physicochemical properties of pure BC and NPs, and their agronomic and environmental applications, specifically including structure design and pyrolysis techniques, water and soil contaminant removal or stabilization, and health risk assessment (Liu et al 2015;Zhang et al 2022c).…”

Biochar (BC) and nanoparticle-decorated biochar (NPs@BC) have emerged as potential high-performance function materials to facilitate simultaneous soil remediation and agricultural production. Therefore, there is an urgent need to incorporate environmental sustainability and human health targets into BC and NPs@BC selection and design processes. In contrast to extensive research on the preparation, modification, and environmental application of BC to soil ecosystems, reports about the adapted framework and material selection strategy of NPs@BC under environmental and human health considerations are still limited. Nevertheless, few studies systematically explored the impact of NPs@BC on soil ecosystems, including soil biota, geochemical properties, and nutrient cycles, which are critical for large-scale utilization as a multifunctional product. The main objective of this systematic literature review is to show the high degrees of contaminant removal for different heavy metals and organic pollutants, and to quantify the economic, environmental, and toxicological outcomes of NPs@BC in the context of sustainable agriculture. To address this need, in this review, we summarized synthesis techniques and characterization, and highlighted a linkage between the evolution of NPs@BC properties with the framework for sustainable NPs@BC selection and design based on environmental effects, hazards, and economic considerations. Then, research advances in contaminant remediation for heavy metals and organic pollutants of NPs@BC are minutely discussed. Eventually, NPs@BC positively acts on sustainable agriculture, which is declared. In the meantime, evaluating from the perspective of plant growth, soil characterizations as well as carbon and nitrogen cycle was conducted, which is critical for comprehending the NPs@BC environmental sustainability. Our work may develop a potential framework that can inform decision-making for the use of NPs@BC to facilitate promising environmental applications and prevent unintended consequences, and is expected to guide and boost the development of highly efficient NPs@BC for sustainable agriculture and environmental applications.
