“…3 (a), it is discernible that the adsorptive uptake of NRFX by various adsorbents were most suitably described by Langmuir isotherm (57%), followed by Freundlich isotherm (26%). This implies that NRFX adsorption is majorly monolayer in nature, where active sites exhibit uniform affinity for NRFX molecules [ 1 , 142 ]. However, NRFX uptake can involve multilayer adsorption occurring on heterogeneous surfaces, which form the main assumptions of Freundlich isotherm observed in 26% of the reviewed works (see Fig.…”

“…The sorbent is a key component of the adsorption technology that determines its efficacy for a target pollutant. In an attempt to find effective sorbents, several materials have been investigated for CIP adsorption, namely activated carbon [31], carbon nanotubes [32], graphene oxide [33], aluminum [34], iron oxides [35], montmorillonite [36], kaolinite [37], birnessite [38] and polysaccharides [39,40].…”

The efficient removal of the antibiotic ciprofloxacin (CIP) from aqueous samples using magnetic nanosorbents prepared using three sulfated polysaccharides, κ-, ι-and λ-carrageenan and an alkoxysilane agent containing a reactive epoxide ring is described. The prepared nanosorbents were characterized in detail using FTIR spectroscopy, solid-state 29 Si and 13 C NMR spectroscopy and elemental microanalysis. The synthesis method was more effective for incorporating higher amounts of κ-carrageenan in the siliceous shells. Although being less sulfated, κ-carrageenan is cheaper than the other carrageenan tested. The CIP adsorption was a cooperative process, well described by the Dubinin-Radushkevich isotherm, with maximum adsorption capacities of 878, 969 and 865 mg/g for κ-, ι-and λ-carrageenan sorbents, respectively. Overall, the produced magnetic nanosorbents are among the best magnetic systems with high adsorptive efficiency for CIP. It is suggested that protonated CIP molecules are exchanged with ester sulfate counterions of carrageenan at the particles' surface as the main pathway for CIP adsorption. The adsorption process was exothermic and entropically favorable for the three sorbents. However, at 298 K, the adsorption was spontaneous for κ-carrageenan-based sorbents and non-spontaneous for ι-and λ-carrageenan particles. The magnetic sorbents could be reused and maintained their ability towards CIP removal up to four cycles. The removal efficiency in wastewater was enhanced with the sorbent dose.

Background: As one of the modal antibiotics in life, the abuse of tetracycline (TC) caused great risks to the ecological environment and health. Cost-effective removal method of TC in the medical wastewater was a developmental research direction with great potential.Results: In this work, a novel material, modified kaolin/β-cyclodextrin (β-CD) coated A (A is a special oxidant made from our laboratory, which is mainly composed of potassium ferrate) was synthesized and characterized. Meanwhile, the removal efficiencies and influencing factors of TC in novel material activation reaction systems were systematically studied. The specific surface area of modified kaolin (MMK) can reach up to 431.82 m 2 /g after acid and calcination modification. The results of SEM, TEM, XRD, and FT-IR showed the significant increase in specific surface area of MMK was the complete destruction of kaolin structure and the leaching of aluminum. β-CD was selected to coat A to attenuate the rapid release of A in water. The optimal coat molar ratio of β-CD and A was 10: 1 (β-CD:A). MMK/β-CD-A was used to treat the simulated TC wastewater, the removal efficiency was 95.6 % within 90 min when the concentration of TC was 0.22 mmol/L. The removal mechanism of TC with MMK/β-CD-A was the adsorption effect from MMK and the oxidation effect from β-CD-A. Conclusion:This work could provide useful information for developing a simple and effective technology to treat TC in medical wastewater.
