“…Considering the concentration of CIP used, similar regeneration phenomena were reported by Elessawy et al 85 . Although studies are difficult to compare due to the differences in their various experimental parameters, it may be said that the sorption and/or desorption efficiencies in this study are much higher compared to other studies reported for CIP removal 86‐88 …”

BACKGROUND The fluoroquinolone antibiotics in water sources are significant threats to public health, as well as the water ecosystem and water reuse. In this study, the feasibility of the biosorption of ciprofloxacin (CIP) using pine needles biomass‐Gibberella fujikuroi immobilized biocomposite (PNGFB) was promoted. It was prepared by passive cell immobilization onto the lignocellulosic matrix. The suggested biosorbent was characterized by Fourier Transform Infrared (FTIR) analysis, Scanning Electron Microscope (SEM), and zeta potential analysis. Series of batch and continuous mode experiments were conducted. RESULTS The results of both systems showed that the PNGFB was effectively used for the treatment of CIP contamination. The maximum uptake occurred at pH 6.0, 40 min contact time, 1.0 mL min−1 flow rate, and 0.10 g (batch) and 0.20 g (column) PNGFB dosages. Redlich–Peterson isotherm model was the best suited to equilibrium data and the pseudo‐second‐order model predicted the biosorption kinetics. The maximum monolayer biosorption capability was 39.17 mg g−1. The suggested biocomposite also reached CIP removal yields of 64.14% and 53.74% in synthetic hospital effluent and synthetic urine samples containing 100 mg L−1 antibiotic, respectively. The regeneration study indicates that PNGFB retained its high biosorption and desorption yields during five cycles of the biosorption‐desorption. CONCLUSION The findings clearly showed that the PNGFB seems to be an eco‐friendly, effective, economic, and potentially viable biocomposite sorbent for the sustainable removal of CIP contamination. © 2021 Society of Chemical Industry (SCI).

“…It is noticeable that contrary to adsorption efficiency, the adsorbent capacity increased dramatically by dye concentration in the studied range, from ~ 44 to ~ 101 mg/g, and from ~ 62.4 to ~ 231 mg/g for MOF-5 and ACS-RGO, respectively. Similar observations were reported for dye eriochrome black-T removal onto ZIF-67-OAc 56 , caffeine removal by oxidized carbon 57 , Cr(VI) removal by fly ash 58 , antibiotics 59 removals by MOFs, direct Blue-71 removal onto multi-walled carbon nanotubes 60 , and in advance oxidation processes such as petroleum hydrocarbons degradation by ozonation 61 .…”

Among cationic dyes, malachite green (MG) is commonly used for dying purposes and also as an inhibitor in aquaculture, food, health, and chemical industries due to its cytotoxic effects. Therefore, MG removal is essential to keep the ecosystem and human health safety. Adsorption is a viable and versatile option and exploring efficient adsorbents have high priority. Herein, MOF-5 and aminated corn Stover reduced graphene oxide (ACS-RGO) of typical adsorbents of metal–organic-frameworks (MOFs) and carbon-based classes were studied for MG removal. MOF-5 and ACS-RGO had a specific surface area and total pore volume of 507.4 and 389.0 m2/g, and 0.271 cm3/g and 0.273 cm3/g, respectively. ACS-RGO was superior for MG adsorption and the kinetic rate coefficient for ACS-RGO was ~ 7.2 times compared to MOF-5. For ACS-RGO, MG removal remained high (> 94%) in a wide range of pH. However, dye removal was pH-dependent for MOF-5 and increased from ~ 32% to ~ 67% by increasing pH from 4 to 12. Increasing dye concentration from 25 mg/L to 100 mg/L decreased adsorption by MOF-5 and ACS-RGO for ~ 30% and 7%, respectively. Dye removal was evident in a few tens of seconds after adding ACS-RGO at doses above 0.5 g/L. A significant loss of 46% in adsorption was observed by decreasing MOF-5 mass from 1 to 0.1 g/L. ACS-RGO removed MG in multilayer with an exceptional adsorption capacity of 1088.27 mg/g. In conclusion, ACS-RGO, and MOF-5 showed promising kinetic rates and adsorption capacities toward MG.

Some environmental problems caused by the intrusion of active drug ingredients, especially antibiotics, into water resources pose a serious threat. Ciprofloxacin (CIP) is an antibiotic from the group of fluoroquinolones that is used extensively in the treatment of bacterial infections. The presence of drug residues in the environment, especially in water resources, is an essential issue due to their stability and nondegradability. This study is aimed at investigating the efficiency of magnetite (Fe3O4) nanoparticles and the effect of independent variables, including initial concentrations of CIP (35-80 mg/L), adsorbent doses (20–60 mg), and pH values (4–10) at reaction time (80 min) for the removal efficiency of CIP antibiotics based on the Box-Behnken design (BBD) method. The analysis of variance (ANOVA) results indicated that a quadratic model was convenient for modeling CIP removal. The first step, the coprecipitation method, was appropriate for the preparation of Fe3O4 nanoparticles and developed as highly efficient adsorbents. Synthesized nanoparticles were later characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier transform infrared spectra (FT-IR). The results of XRD have shown that angles for the peaks at 2 θ = 30 , 35.22 , 43.35 , 53.68 , 57 , 62.79 , and 71.38 deg , which corresponded to the crystal planes 220, 311, 400, 422, 511, 440, and 535, respectively, were consistent with standard peaks of magnetite and a cubic face structure. The obtained results indicated that the CIP removal efficiency was 74.44% under optimum operation parameters: initial concentration of CIP 44.15 (mg/L), adsorbent dosage of 59.6 (mg), pH ≅ 5 , and contact time of 80 min. In fact, a cooperative agreement between model prediction and experimental data using BBD with significant R 2 values of 0.95 was observed. Based on the results, magnetite nanoparticles have an excellent ability to remove antibiotics from an aqueous phase.
