“…Antibiotics are partially metabolized in the body, and 30-90% of them remain active after excretion (Malakootian et al 2019c). These compounds are found in different scales of nano-to micrograms per liter in various drinking water, groundwater, surface water, sewage, and wastewater sources (Javid et al 2019).…”

Ciprofloxacin (CIP) is a commonly used antibiotic which is excreted in significant quantities and may likely be found in environments, especially wastewater. Thus, in the present study, we aimed to remove CIP from aqueous solutions using activated carbon supported with multivalent carbon nanotubes MWCNTs/AC. Herein, we prepared the MWCNTs/AC and the structural characterization of the adsorbent was performed using the BET, FTIR, and SEM methods. In order to obtain the optimal conditions of MWCNTs/AC activity, different experimental conditions including the pH, adsorbent dosage, contact time, initial CIP concentration, and temperature were examined. Afterward, to approach reality, the experiments were carried out under the optimal conditions using a sewage sample previously determined in terms of the BOD, COD, pH, EC, turbidity, and concentration of ciprofloxacin. Finally, the CIP levels were measured by HPLC. According to the results, the pH of 7, contact time of 30 min, adsorbent dosage of 20 mg/L, temperature of 40 °C, and initial CIP concentration of 20 mg/L were found to be the optimal conditions for MWCNTs/AC activity. In these conditions, the maximum removal efficiency of CIP from the synthetic and actual samples was 100% and 73%, respectively. Moreover, the adsorption behavior was in compliance with the pseudo-second-order, Freundlich isotherm kinetics. According to our findings, using MWCNTs/AC led to a considerable removal of CIP from the sewage samples. Thus, the use of this adsorbent is highly recommended in order to remove other antibiotics from water and wastewater.

“…The presence of antibiotics in the aquatic media may cause toxic effects on non‐target organisms, as well as disruption of the biological balance and photosynthetic cycles of plants occur . Non‐biodegradable property of some antibiotics makes them remain in the environment for a long time . So, the removal of them from aqueous media is significant.…”

The present study, a novel and efficient adsorbent nano zerovalent iron stabilized on strontium hexaferrite (nZVI/SrFe 12 O 19 ) was synthesized for removal of ceftriaxone antibiotic from aqueous solution. Its characteristics were analyzed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive Xray spectroscopy (EDX). Response Surface Methodology (RSM) based on Box-Behnken Design (BBD) were used to achieve the optimal experimental conditions. The effects of parameters such as pH (5-9), initial concentration of ceftriaxone (5-15 mg L À 1 ), and adsorbent dosage (0.05-0.15 g L À 1 ) on removal efficiency were investigated. A mathematical model was studied to predict the removal performance. The significance and adequacy of the model were surveyed using analysis of variance (ANOVA). The results showed that second-order polynomial model is suitable for the prediction removal of ceftriaxone. The highest removal value of mentioned drug were obtained 98 % at adsorbent dosage of 0.15 g L À 1 , pH = 5, and the pollutant concentration of 10 mg L À 1 . Finally, the isotherms and kinetic studies were evaluated. The Langmuir with R 2 = 0.9981 and pseudo-second-order with R 2 = 0.9996 were the best isotherm and kinetic, respectively. The thermodynamic parameters such as ΔH 0 , ΔS 0 , and ΔG 0 were calculated and it was indicated that adsorption process was exothermic and spontaneous.[a] Dr.
