“…In other words, the higher the concentration of tetracycline, the more diffusion would consist from the polymer surface to the pores [51]. Similar behavior for the impact of tetracycline concentrations on the uptake capacity of tetracycline was observed and discussed for different adsorbents in the literature [52][53][54]50].…”

In present study, graft copolymer was synthesized by free radical method using N-tertiary butylacrylamide monomer on chitosan which is an environment friendly polymer. The chemical structure and the surface morphology of the newly synthesized graft copolymer were determined by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). Thermal behavior was analyzed by thermogravimetric analysis (TGA). To investigate the applicability of chitosan-graft-poly(N‑tert‑butylacrylamide) graft copolymer, it was used as an adsorbent for rapidly removal of tetracycline from aqueous solution. Response surface methodology (RSM) was employed for the optimization of the study conditions such as adsorbent dosage (0.01–0.04 g), reaction time (10–90 minutes), and initial tetracycline concentration (10–100 mg 100 mL− 1). The effects of these conditions on tetracycline uptake capacity were examined by RSM and the results were statistically analyzed. The RSM results showed that maximum tetracycline uptake capacity (104.81 mg g− 1) was achieved at the adsorbent dose of 0.03 mg 100 mL− 1, reaction time of 51.12 minutes, and initial tetracycline concentration of 97.99 mg L− 1. ANOVA analysis based on central composite design combined with RSM showed good agreement between experimental values and quadratic model estimates, thus resulting in 0.9118 R2 for tetracycline uptake. The findings demonstrated chitosan-graft-poly(N‑tert‑butylacrylamide) copolymer is an effective adsorbent for pharmaceutical wastewater treatment.

“…126 Due to the broader application and lesser cost for production of ZnO NPs, they are useful for antibiotic sequestration; the novel ZnOcoated pistachio shell could remove TC with Q m of 95.06. 127 In situ bentonite-supported nZVI-Cu, synthesized using pomegranate peel extract as a reducing agent, has 95% TC removal capacity with enhanced stability and environmental sustainability. 128 Similarly, in situ sand-coated GS-NiFe packed in a xed-bed column reactor was used for the continuous removal of TC from wastewater, and it was conrmed that the external mass transfer during the initial stage was the inuencing factor for TC removal, and the maximum TC loading capacity of adsorbent was 978 AE 5 mg g À1 .…”

“…Recently, extensive research has been conducted on the removal of pharmaceutical contaminants, using photocatalytic and adsorbent materials that are biophilic and without any secondary contamination [9][10][11][12]. Adsorption processes can be performed through interactions between molecules of contaminants and adsorbents and mainly include hydrogen bonding, electrostatic bonding interactions and π-π interactions [13][14][15][16][17].…”

Today, environmental pollutants pose a threat to human societies and all living organisms, which is why they have attracted the attention of environmental researchers. In this study, in order to remove pharmaceutical contaminants Naproxen and Amoxicillin from aqueous media with SiO2 nanoparticles based on Agar and Chitosan was investigated. The study of structural properties, physical and chemical characterization of synthesized nanocomposite was investigated by FTIR, XRD, TEM, FE-SEM, DLS and EDX analyzes. In addition, the role of parameters affecting the removal of pharmaceutical contaminants such as solution pH, contact time, contaminant concentration and temperature were studied. Nanocomposites prepared from Agar and Chitosan showed good performance in absorbing naproxen and amoxicillin. According to the studies performed to remove naproxen, the max adsorption efficiency was obtained at a concentration of 20 mg/l with an absorbent dose of 0.05 g and a pH of 8 and at an optimum temperature of 25 °C and 99% in 15 min. Also, for amoxicillin with nanocomposite prepared with an initial concentration of 20 mg/l and an adsorbent dose of 0.05 g, a time of 10 min, a temperature of 25 °C and a pH of 8, the max removal efficiency of 91.15% was obtained.
