“…As illustrated in Table 3, removal of sulfamethoxazole were in the range of 12% for two types of wood feedstock, while using sugarcane as the feedstock produced a biochar able to achieve removal up to 21% [79]. Using rice husk and rice straw as the feedstock, sulfamethoxazole removal was as low as 11.6% except when using alkali treated rice husk feedstock where almost 30% removal was achieved [67].…”

“…Using rice husk and rice straw as the feedstock, sulfamethoxazole removal was as low as 11.6% except when using alkali treated rice husk feedstock where almost 30% removal was achieved [67]. The carbon, nitrogen and phosphorus content in the feedstock has been found to create significant differences in the treatment performance of biochar [67,79].…”

“…[11][12][13] Several studies have also demonstrated that biochars have strong sorption ability to organic contaminants including pesticides and pharmaceuticals, and their sorption capacities are much higher than that of soils. [11,14,15] Compared with heavy metals and organics, less research effort has been dedicated to investigate the removal of nutrients such as ammonium by biochars derived from agricultural residues. [16] Steiner et al [17] found that biochar produced from pine chips can reduce the ammonium emissions from N-rich composts because the strong sorption ability of the biochar to gaseous NH 3 and aqueous ammonium ions.…”

Water contamination by ammonium ions presents huge risks to the ecosystems. This work evaluated the potential of biochar as an alternative adsorbent to remove ammonium from aqueous solutions. Nine types of biochars were converted from three types of agricultural residuals at three pyrolysis temperatures. Batch sorption experiment showed that all the biochars effectively removed ammonium ions from water. The biochars produced at low pyrolysis temperatures, however, showed higher sorption of ammonium. The low-temperature biochars showed relatively fast sorption kinetics of ammonium, which reached equilibrium around 10 h. Sorption isotherms showed that the low-temperature biochars had high sorption capacities to the ammonium, and the Langmuir maximum capacities were all higher than 200 mg/g. Batch sorption experiments also showed the sorption of ammonium onto the biochar was affected by pH and temperature, but not by ionic strength. The biochar showed good sorption ability to ammonium in aqueous solutions under all of the tested conditions. Findings from this work indicated that biochar could be used as an alternative adsorbent for the treatment of ammonium in water.

“…The addition of biochars to soils has been assessed to be an effective practice in sequestering carbon (Lehmann 2007), increasing soil fertility (Van Zwieten et al 2010) and crop production (Major et al 2010), reducing green house gas emissions (Lehmann et al 2006), and also improving soil microbial activity (Steiner et al 2008). Recently, biochar has been reported to be particularly effective in sorption and sequestration of organic contaminants, such as polycyclic aromatic hydrocarbons (Chen and Yuan 2011), diuron (Yu et al 2006), atrazine and simazine (Zheng et al 2010), pentachlorophenol (Devi and Saroha 2015), phenanthrene (Zhang et al 2010), oxytetracycline (Jia et al 2013), sulfamethoxazole (Yao et al 2012;Lian et al 2014), and sulfamethazine (Rajapaksha et al 2014;Rajapaksha et al 2015).…”

Biochars (BC) generated from biomass residues have been recognized as effective sorbents for organic compounds. In this study, biochars as adsorbents for the removal of norfloxacin (NOR) from aqueous solutions were evaluated. Biochars were prepared from cassava dregs at 350 °C, 450 °C, 550 °C, 650 °C, and 750 °C, respectively (labeled as BC350, BC450, BC550, BC650, and BC750). The results showed that the kinetic data were best fitted to the pseudo second-order model, indicating that the sorption was governed by the availability of sorption sites on the biochar surfaces rather than the NOR concentration in the solution. Sorption isotherms of NOR were well described by the Freundlich model, and the Freundlich coefficients (lgkF) increased with the pyrolysis temperature of biochars. Thermodynamic analysis indicated the feasibility and spontaneity of the NOR adsorption process. The NOR adsorption on BC450, BC550, BC650, and BC750 was an endothermic process, while an exothermic process occurred for BC350. FTIR studies further suggested that the adsorption mechanism was possibly attributable to H-bond and π-π interactions between NOR and biochars. Overall, this work constitutes a basis for further research considering the bioavailability and toxicity of antibiotics in the presence of biochar.
