“…The biochar surface functional groups were measured with FTIR before and after adsorption of NOR according to Jia et al (2013). After achieving sorption equilibrium, the suspensions were allowed to stand for 24 h, and then the suspensions were removed.…”

“…The high R 2 values (0.969 to 0.998) suggested that the Freundlich model simulated the adsorption of NOR on the biochars well. As shown in Table 3, for BC350, BC650, and BC750, the sorption of NOR was highly nonlinear, with 1/n in the range of 3.26 to 64.93 (more than 1) at different temperatures, suggesting that the heterogeneous surfaces of biochars were bonded to NOR by weak free energies so that sorption is essentially dominated by adsorption rather than partitioning (Jia et al 2013). On the other hand, the values of 1/n for BC450 and BC550 were relatively close to 1, indicating that the sorption was led by partitioning, which was consistent with the adsorption isotherms.…”

“…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.

“…Clomazone [2-(2-chlorobenzyl)-4,4-dimethyl-1,2-oxazolidin-3-one] is an herbicide from the oxazolidinone chemical group and has a wide spectrum for pre-and post-emergence control of monocots and dicots in sugarcane cultures (ANVISA, 2016). In soil solution, it tends to remain in its molecular form because it is a non-ionizable herbicide (Jia et al, 2013). However, non-ionic herbicide behaviors may be influenced by the changes that pH alteration causes in clay mineral complexes and in the organic matter of soil (Silva et al, 2007).…”

Clomazone Leaching Estimate in Soil Columns Using the Biological Method

-The chemical control of weed is a necessary practice in large-scale agriculture. However, when herbicides are used in the wrong way, they can remain into soil for long periods and/or be leached in its profile, and they may even contaminate groundwater. In this research, clomazone leaching in soil samples collected from different Brazilian regions was estimated by biological method. To do so, columns containing soils were used, and samples were collected every 5 cm. After preparing columns and applying a 1,500 g a.i. ha -1 clomazone dose, rain simulation was performed. Sorghum was used in order to detect the herbicide. More than 60% similarity was found for the studied variables; it was chosen to use only data referring to toxicity percentage. Clomazone did not cause reduction in sorghum cultivated in Organosol, thus indicating a strong herbicide sorption in this soil. Increased pH in Oxisol reduced leaching. More rainfall caused increased herbicide leaching in Oxisol (pH 5.1) and Quartzarenic Neosol. The highest leaching occurred in soils with lower pH and lower organic matter content. It is possible to conclude that, in soils with higher organic matter content, clomazone has lower risks of being leached.Keywords: herbicide, mobility in soil, environmental impact.

“…Their findings indicated that soil organic matter and clay are effective in the sorption of OTC and its potential availability. Jia et al (24) showed that the sorption of OTC on biochar depends highly on the pH of the solution. Their results also indicated the enhancement of sorption by the presence of Cu 2+ ions.…”

Role of organic matter, clay, and iron contents in the sorption of oxytetracycline on river sediments

Background: Oxytetracycline (OTC) is a widely-used antibiotic; metabolism studies indicate only partial assimilation of it inside the body. Traditional wastewater treatment plants cannot remove OTC, and this results in the release of considerable amounts of the drug into aquatic environments. There is much concern over the role of residual antibiotics in the development of new generations of bacteria with modified resistance to the antibiotics. The present work investigated the possibility of OTC sorption on river sediments. Methods: Seven sediment samples were collected from various locations and depths of the Passaic River in New Jersey. The texture, clay, extractable iron, and organic matter contents of the sediments were determined. Pyrolysis-gas chromatography-mass spectrometric (Py GC-MS) analysis indicated the presence of 3 categories of organic materials: petroleum hydrocarbons, anthropogenic, and plant residual materials. The sediment samples were equilibrated with OTC solutions for 24 hours followed by centrifugation and syringe filtration. The residual OTC contents were determined by high performance liquid chromatography. Results: It appeared that 35%-60% fractions of OTC were retained by the sediments. The sorption capacity values of the sediments were correlated with clay content, organic matter content, and available iron. A poor correlation was found between adsorption capacity and clay content in the presence of organic matter and iron. Meanwhile, a relatively strong correlation was found between adsorption capacity with the iron, R 2 = 0.7499, and organic matter contents of the sediments, R 2 = 0.7899. Thus, the sorption of OTC on sediments is governed by all constituents. Conclusion: It was concluded that the antibiotic-sediment interaction is controlled mainly by the organic matter and iron contents.
