“…For norfloxacin, at pH below 6.10 the positively charged form of the molecule is dominant, while at pH between 6.2 and 8.5, the zwitterionic form becomes dominant. [32] Soil pH could change the species composition of norfloxacin, resulting in different behavior and effects. The effect of pH value on degradation of norfloxacin should also be considered in future studies.…”

This paper investigated the degradation kinetics of norfloxacin in a soil, and its effects on soil respiration and nitrogen transformation under different conditions. Compared to the sterile control, the degradation rates of norfloxacin in the non-sterile soil were greatly enhanced, suggesting that microorganisms played a major role in the degradation. Accelerated degradation for norfloxacin in the soil was observed with decreasing concentrations (30 mg/kg to 5 mg/kg) with its half-life decreasing from 62 days to 31 days. Amending swine manure into the soil and increasing the soil moisture level enhanced the biological degradation of norfloxacin. No obvious inhibition of norfloxacin on soil respiration was observed in the soil, while only slight effect on nitrogen transformation was found. The results suggested that norfloxacin at the reported environmental concentrations (<100 mg/kg) would have little effect on microbial activity and functions in the soils.

“…Some 254 pharmaceuticals contain nitrogen-containing functional groups which are basic 255 and will therefore be readily protonated to give a cation under certain conditions 256 [19,20]. To evaluate the cation-exchange properties of the HXLPP-WCX 257 sorbent, and establish the scope of its sorption characteristics, we selected a 258 group of acidic and basic pharmaceuticals with variable pK a values (Table 1).…”

“…Many techniques have been investigated for NOR decontamination, including adsorption (Lorphensri et al 2006), photodegradation , and chlorine oxidation (Dodd et al 2005), among which adsorption is considered to be a simple and effective method to remove NOR. Previous research on adsorption of fluoroquinolone antimicrobials by different environmental matrices has included silica, alumina (Lorphensri et al 2006), soils (MacKay and Seremet 2008), clay minerals (Figueroa-Diva et al 2010), natural aquifer material (Hari et al 2005), oxide minerals (Gu and Karthikeyan 2005), carbon nanotubes , and activated carbon (Liu et al 2011;Carabineiro et al 2011;Ahmed and Theydan 2011), but few studies about its sorption by biochar have been done.…”

Generally, the adsorption mechanisms of fluoroquinolone antimicrobials with model sorbent phases have been documented to be cation exchange, cation bridging, surface complexation, hydrophobic effect, electrostatic interaction, and electron-donor-acceptor interactions .…”

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.
