“…Both acid and alkaline modifications can improve the physical and chemical properties and removal rate of BC. For example, Luo et al (2018) used KOH modified BC to remove norfloxacin (NOR), sulfadiazine (SMR), and oxytetracycline (OTC). The surface area increased from 75.3 to 128.42 m 2 /g and the removal rates of NOR, SMR, and OTC were all significantly enhanced.…”

Biochar (BC) has exhibited a great potential to remove water contaminants due to its wide availability of raw materials, high surface area, developed pore structure, and low cost. However, the application of BC for water remediation has many limitations. Driven by the intense desire of overcoming unfavorable factors, a growing number of researchers have carried out to produce BC-based composite materials, which not only improved the physicochemical properties of BC, but also obtained a new composite material which combined the advantages of BC and other materials. This article reviewed previous researches on BC and BC-based composite materials, and discussed in terms of the preparation methods, the physicochemical properties, the performance of contaminant removal, and underlying adsorption mechanisms. Then the recent research progress in the removal of inorganic and organic contaminants by BC and BC-based materials was also systematically reviewed. Although BC-based composite materials have shown high performance in inorganic or organic pollutants removal, the potential risks (such as stability and biological toxicity) still need to be noticed and further study. At the end of this review, future prospects for the synthesis and application of BC and BC-based materials were proposed. This review will help the new researchers systematically understand the research progress of BC and BC-based composite materials in environmental remediation.

“…Thus, the polarized electron-rich graphite surface of biochar can act as a π-electrondonor, while TC molecules act as the effective π-electron-acceptor for their strong electron-withdrawing ability on ketone group and aromatic ring structure [31]. Additionally, High temperature carbonization would promote the formation of graphene structures in biochar, which would further enhance the π-π EDA interaction between biochar and TC [37]. This may be an important reason why the sorption capacity of TC on RB600 was larger than RB450.…”

To determine the sorption potential and mechanisms of tetracycline (TC) on pristine and H 2 O 2-modified biochars, rape stalk biochars were produced and modified by H 2 O 2. The specific surface area and pore volume of biochars increased with improving pyrolysis temperature, while the acidic groups decreased. Moreover, modified by H 2 O 2 , much more oxygen-containing functional groups were introduced. The results of sorption dynamics and isothermals tests showed that RB300 had the largest TC sorption capacity of 35.90 mg/ g, which was ascribed to a plenty of non-carbonized organic matter and surface functional groups were retained. Modified by H 2 O 2 , the sorption of TC on biochars was enhanced which indicated the dominated sorption mechanisms were H-bonding and π-π electron donor acceptor interaction. The pH value would impact on sorption, and the maximum sorption capacity was obtained at pH = 9.0. Both cation concentration and type would affect the TC sorption.

“…Additionally, this suggested that the multiple H‐bonds and π–π interactions between cefdinir and WL‐BC‐OH may have had some contribution. [ 43 ] As discussed previously, the effects of the increased surface area and the aforementioned mechanisms could have dominated the adsorption affinity.…”

Cefdinir adsorption onto non‐activated biochar (WL‐BC) and activated biochars (WL‐BC‐H, WL‐BC‐OH) prepared from waste biomass (WL) is comparatively investigated in view of adsorption factors, adsorption isotherms and adsorption kinetics. Batch experiments are conducted to assess the effects of pH, adsorption time and initial antibiotic concentration. Various advanced techniques are applied to characterize the prepared biochars (BCs). Characterization of the new BCs reveal that the activation process do not have a significant effect on the chemical structure of activated carbons, but it increases the surface area up to eight times. The equilibrium data are simulated with the Langmuir adsorption model indicating monolayer adsorption for both activated biochars WL‐BC and WL‐BC‐H. However, the adsorption isotherm for WL‐BC‐OH is represented well by the Freundlich model, which shows that multilayer adsorption took place. The kinetic data are analyzed using various kinetic models. The maximum adsorption capacity of the activated biochar is approximately tenfold in comparison to the non‐activated biochar. Additionally, the real wastewater experiments with treated campus wastewater show that the adsorptive performance of the activated biochar is not affected by other ions. Consequently, BCs derived from defatted laurel leaves could be effective and eco‐friendly adsorbents for removing cefdinir from wastewater.
