“…Hematite and goethite are the most commonly employed Fe minerals to increase the adsorption efficiency of biochar for heavy metals such as Hg, As, Cr, Cu, Pb, and Cd 134 . Lima et al 135 produced the goethite-modified biochar and observed maximum sorption capacities for As 3+ and Cd 2+ were 78 mg g −1 and 63 mg g −1 , respectively. Baser et al 40 synthesized three types of Fe-activated biochars including Fe 3 O 4 - modified biochar, Fe 2 O 3 - activated biochar, and Fe-treated biochar via one-step ball milling of magnetite, ferric oxide, and iron powder, respectively.…”

The pollution of soil and aquatic systems by inorganic and organic chemicals has become a global concern. Economical, eco-friendly, and sustainable solutions are direly required to alleviate the deleterious effects of these chemicals to ensure human well-being and environmental sustainability. In recent decades, biochar has emerged as an efficient material encompassing huge potential to decontaminate a wide range of pollutants from soil and aquatic systems. However, the application of raw biochars for pollutant remediation is confronting a major challenge of not getting the desired decontamination results due to its specific properties. Thus, multiple functionalizing/modification techniques have been introduced to alter the physicochemical and molecular attributes of biochars to increase their efficacy in environmental remediation. This review provides a comprehensive overview of the latest advancements in developing multiple functionalized/modified biochars via biological and other physiochemical techniques. Related mechanisms and further applications of multiple modified biochar in soil and water systems remediation have been discussed and summarized. Furthermore, existing research gaps and challenges are discussed, as well as further study needs are suggested. This work epitomizes the scientific prospects for a complete understanding of employing modified biochar as an efficient candidate for the decontamination of polluted soil and water systems for regenerative development.

“…Hence, the new approach to the regeneration of biochar is based on catalytic oxidation (e.g. Fenton reaction) leading to the degradation of the adsorbate [208]. The effectiveness of all of these methods depends on many factors of which the most important are the type of adsorbent and interactions between adsorbent and adsorbate (e.g.…”

Antibiotic contamination and the spread of antimicrobial resistant bacteria are global environmental issues. Given the growing consumption of antibiotics, it is crucial to reduce their presence in the environment. Adsorption is one of the most efficient methods for removing contaminants from water and wastewater. For this process to be effective, it is of key importance to identify adsorption mechanisms that allow an efficient and selective adsorbent to be chosen.Carbon-based materials (including activated carbon, biochar and black carbon) are typically used for the adsorptive removal of antibiotics. To enhance the efficiency of adsorption of pharmaceuticals, engineered biochars (physically, chemically and biologically modified biochar) and their composites have attracted increasing interests. Biochar-based sorbents can be produced from various feedstocks, including waste products. The use of "green", low cost or sustainable biochar for contaminant sorption yields economic and environmental benefits.Moreover, this is in line with global trends in creating a circular economy and sustainable development. This paper collates the most recent data on the consumption of antibiotics, their related environmental contamination, and their removal using biochar-based materials. Special attention is paid to the newly emerging approaches of biochar modification and biochar composites in relation to the antibiotic removal from water.
