AB  - The use of antibiotics constantly increases which has a notable negative impact on water bodies. Ciprofloxacin (CIP) is widely applied
antibiotic in both human and veterinary medicine, as well as in a livestock breeding. Due to its extensive use, CIP has been found in
wastewater effluents in a wide concentration range from ng to mg dm^(–3). An extremely high concentration of up to 50 mg dm^(–3)
has been found near drug manufacturing plants [1]. Since CIP, as well as many other pharmaceuticals, cannot be efficiently removed
from wastewater streams by conventional wastewater treatments, it is of a great importance to find an acceptable method for their
removal.
This study reports the use of natural calcium-rich clinoptilolite (CLI) for the adsorption of CIP and regeneration of the spent adsorbent
(CLI-CIP) by non-thermal atmospheric pressure plasma (NTP). The results show that the CLI possesses a high adsorption efficiency in
removal of CIP at 283, 288 and 293 K in a slightly acidic medium (pH= 5) for the initial concentrations from 15 to 75 mg dm^(–3). The
CIP adsorption by CLI follows the Lagergren’s pseudo-second-order kinetics and it can be described well by the Langmuir isotherm
model. For all studied temperatures and initial concentrations more than 85% of the CIP is removed within the first 10 minutes. The
results also indicate that the CIP adsorption mechanism includes two phenomena: 1) electrostatic interactions between negatively
charged aluminosilicate lattice and cationic form of CIP species and 2) ion-exchange reaction.
The use of NTP for the regeneration of CLI-CIP was based on the assumption that NTP generates highly reactive species which can
induce a cleavage of the bonds formed between active sites on the CLI surface and CIP, and also induce the CIP decomposition. The
NTP treatment was performed for a short time, with a low energy consumption, and without using the additional chemicals. All these
make the procedure acceptable not only from economical point of view but also regarding environmental issues [2].
A surface dielectric barrier discharge plasma source was used for the treatment of CLI-CIP. The regeneration study was consisted of five
successive adsorption/NTP cycles. Powder X-ray diffraction and Brunauer–Emmett–Teller surface area analyses confirmed that the
plasma treatment did not influence the CLI lattice nor its textural properties. Moreover, X-ray photoelectron spectroscopy confirmed
that the NTP reduces carbon content in the regenerated CLI for more than 90% and that the plasma reactive species are involved in the
CLI regeneration process.
The obtained results strongly support the applicability of the NTP treatment in regeneration of zeolite-based adsorbents used in
pharmaceutical removal from wastewater.

AB  - The adsorption of the antibiotic ciprofloxacin (CIP) from water solution by natural zeolite–clinoptilolite (CLI), magnetic clinoptilolite (MAG-CLI), and graphene oxide coated magnetic clinoptilolite (GO-MAG-CLI) was investigated. The novel approach of an environmentally friendly and cost-effective microwave-assisted method was applied for the magnetic composite synthesis. Detailed characterization of the prepared composites was achieved. In order to investigate the effect of the initial CIP concentration, pH, temperature, contact time, and type of adsorbent on the adsorption efficiency of CIP, and to obtain the optimal conditions for CIP removal, the response surface methodology central composite factorial design (RSM-CCF) was applied. The results obtained by the RSM-CCF showed that among the studied adsorbents, GO-MAG-CLI had the highest adsorption capacity for CIP, achieved for the initial concentration of 48.47 mg dm−3 at a pH of 5 and 24.78 °C after 19.20 min of contact time. The adsorption kinetics studied for the initial CIP concentration range of 15–50 mg dm−3 followed Lagergren’s pseudo-second-order model, and the Langmuir isotherm was the most suitable one to describe the CIP adsorption onto GO-MAG-CLI.

AB  - Natural clinoptilolite (CLI) exhibited a high efficacy in ciprofloxacin (CIP) removal from aqueous solution by adsorption. However, the regeneration of the spent adsorbent was a challenge since the adsorption occurred via electrostatic interactions and ion-exchange reaction. Herein, the feasibility of non-thermal plasma (NTP) was studied for the regeneration of ciprofloxacin-containing clinoptilolite (CIP-CLI) in five successive adsorption/NTP regeneration cycles. The NTP treatments were performed using a surface dielectric barrier discharge (SDBD) operating at atmospheric pressure in air. Plasma discharge gap, sample mass, and electrode surfaces were varied to find optimal regeneration parameters. For the plasma source with an electrode surface of 37.2 cm2, the 2 mm electrode gap and 20 min of plasma treatment were found as optimal parameters (sample mass of 0.2 g). The plasma treatment did not affect clinoptilolite features which were concluded from a study of textural properties and powder X-ray diffraction (PXRD) analysis. X-ray photoelectron spectroscopy (XPS) showed a decrease of total carbon content with around 10% of carbon residual left on the surface. The CLI adsorption capacity can be regenerated to at least 90% of its initial capacity during the five successive cycles, showing the involvement of plasma reactive species in decomposition of adsorbed CIP.

AB  - The adsorption of the antibiotic ciprofloxacin (CIP) from an aqueous solution by natural zeolite, the calcium-rich clinoptilolite (CLI), and magnetite-coated CLI (MAG-CLI) was investigated. Both CLI and MAG-CLI showed a high adsorption affinity towards CIP at 283, 288 and 293 K at a pH of 5. Adsorption kinetics studied for the initial concentrations of 15-75 mg CIP dm(-3) follow Lagergren's pseudo-second order equation and the adsorption is best represented by the Langmuir model. The adsorption mechanism involves strong electrostatic interactions between negatively charged aluminosilicate lattice and the cationic form of CIP accompanied by an ion-exchange reaction. Magnetite coverage (approx. 12 wt.%) induces magnetism, which can facilitate the separation process. The coverage does not influence the adsorption activity of CLI. The leaching test showed that the MAG coating protects the adsorbent from CIP leaching. This is ascribed to interactions between the CIP carboxyl groups and magnetite nano-particles. Antibacterial tests showed strong antibacterial activity of the ciprofloxacin-containing adsorbents towards pathogenic E. coli and S. aureus.

AB  - Natural zeolite – clinoptilolite (CLI) from Serbian deposit Slanci (near the capital city Belgrade) was
investigated as adsorbent for the adsorption of antibiotic ciprofloxacin (CIP) as a model organic micropollutant (OMP) present in wastewater. At 20 °C the adsorption capacity varies from 4.81 to 8.90 mg g-1 for the initial CIP solution concentration of 15 and 50 mg CIP dm–3, respectively. The adsorption isotherms at 10, 15 and 20 °C are best represented by the Langmuir model and the adsorption kinetics by the Lagergren's pseudosecond-order equation. The adsorption mechanism most probably involves an ion-exchange reaction occurred at the CLI surface and according to results of Weber-Morris model does not involve intra-particle diffusion.
