Sažetak
In this study the employment of non-equilibrium plasma processing for regeneration of spent natural zeolite-clinoptilolite adsorbent was investigated in order to recover its adsorption properties. The antibiotic ciprofloxacin was used as a model persistent pollutant. Treatments of the spent clinoptilolite were performed in a surface dielectric barrier discharge operating in air. High-voltage sine signal was supplied to the square-shaped segmented upper electrode separated 2 mm from the lower electrode which served as a sample holder. Simple geometry in the plasma source design allowed scaling up the device in order to study the effect of electrode surface to the zeolite treatment. Recovery of the adsorption potential up to 70% was achieved after 20 minutes of the treatment in the first regeneration cycle. High recovery rates were also obtained in subsequent cycles showing non-equilibrium plasma is a prospective method for recycling the used adsorbent material.
