Preparation of mesoporous batatas biochar via soft-template method for high efficiency removal of tetracycline

Effect of hydrothermal pretreatment on pyrolyzed sludge biochars for tetracycline adsorption

“…Characterization methods of two biochars about the surface morphology, main surface elements, structural characteristics and surface functional groups are consistent with our previous literature report, which is presented in Text S1 [4].…”

“…Tetracycline (TC), for example, is the second most consumed antibiotic in the world and often used as the antibacterial drug and growth promoter in agriculture and animal husbandry [4,5]. However, approximately 80~90% of TC used in organisms are released into the outside of body in the form of parent compound and active metabolites through faeces and urine [6,7].…”

“…Meanwhile, the removal of antibiotics by advanced oxidation processes may produce some undesired by-products, which may be higher toxic than their parental compounds [16]. Hence, adsorption is considered to be a promising and efficient treatment method compared to biological and advanced oxidation processes, with the main advantages of operation simplicity, high efficiency, low cost, and no toxic by-products [4,17]. The focus of the adsorption method is the selection of the adsorbent, and carbonaceous materials consisting of activated carbon, biochar and graphite have received extensive attention due to their high porosity and excellent physical and chemical characteristics, etc [18][19][20][21].…”

Recent advancement of biomass-derived porous carbon based materials for energy and environmental remediation applications

“…For example, Zheng et al fabricated mesoporous carbon material from batatas biomass using F127 (polyethylene-polypropylene glycol) as soft template. 181 Similarly, Sun et al synthesized N, S co-doped honeycomb-like hierarchical porous carbon from chitosan employing a soft-template strategy (Fig. 9d), where F127 and sodium dodecyl sulfate (SDS) acted as soft templates.…”

Preparation of Ce/ferroferric oxide/food waste‐derived biochar for aqueous Cr(VI) adsorption

“…indicating that neither the liquid film nor IPD was the sole step that limit the reaction speed for the two processes (Ma et al, 2021;). Table 3 shows that ki1>ki2>ki3, indicating that external surface diffusion had a larger role in Cr (VI) adsorption by Ce/Fe3O4/FWB (Zheng et al, 2021b). C2 values were greater than C1 values at both beginning concentrations, indicating a thicker boundary layer, and the IPD was the key control for Cr (VI) adsorption (Zheng et al, 2021b).…”
