Effective Remediation of an Antibacterial Drug from Aqua Matrix Using CaFe2O4/ZrO2 Nanocomposite Derived via Inorganic Chemical Pathway: Statistical Modelling by Response Surface Methodology

Recent advancements in CaFe2O4-based composite: Properties, synthesis, and multiple applications

“…For the removal of the TC drug, a CF-ZrO-MNC (calcium ferrite-zirconium oxide magnetic nanocomposite) was created. 86 It has been observed that the TC adsorption on the surface of the catalyst CF-ZrO-MNC entirely depends on the pH. At pH 6.0, CF-ZrO-MNC removed more than 65% of the TC, but the effectiveness dropped further at pH 6.0.…”

“…Nevertheless, at pH 5.0-7.0, TC is accessible in its zwitterion form, including positively charged groups with strong electrostatic attraction to the CF-ZrO-negatively charged MNC's active surface sites. 86 To investigate the reusability and stability of CF-ZrO-MNC, the adsorption-desorption of TC was carried out with CF-ZrO-MNC for five successive runs. At 6.0 pH of solution within 60 min, when the concentration of TC was 40.0 mg/l, the removal efficiency of TC was 98.14%.…”

“…At 6.0 pH of solution within 60 min, when the concentration of TC was 40.0 mg/l, the removal efficiency of TC was 98.14%. 86 The concomitant removal of tetracycline hydrochloride (TCH) coupled with the CF/ Bi 2 O 3 composite has been studied. Within 30 min, the maximum efficiency of removal of TCH was 97.8% using a 24.6 kV peak pulse voltage, an initial pH of 3, a 50 Hz pulse frequency, and an airflow rate of 2 l/min.…”

First investigations on removal of nitrazepam from water using biochar derived from macroalgae low-cost adsorbent: kinetics, isotherms and thermodynamics studies

“…Hence, proper removal of these compounds from the aquatic environment is highly essential. The above facts have been considered by many researchers, and many techniques have been applied for removal of pharmaceutical compounds from wastewater such as adsorption (Naghipour et al 2018;Bhowmik et al 2020;Debnath et al 2020;Zahra et al 2020), ion exchange, precipitation, coagulation, chlorination, sedimentation, sand filtration, biological treatment, membrane separation, advanced oxidation and ozonation (Westerhoff et al 2005;Snyder et al 2007;Ikehata et al 2008). Among these techniques, adsorption is one of the most widely used methods for the removal of pharmaceuticals from water.…”
