Abstract

Copper oxide powders were synthesized using a low-temperature underwater plasma method with varying discharge currents (0.25–0.8 A). The resulting samples were characterized by X-ray phase analysis, scanning electron microscopy, low-temperature nitrogen adsorption, and thermogravimetric analysis, and were evaluated as sorbents. It was observed that the plasma parameters influenced the phase composition and surface structure of the powders but did not affect their surface morphology. All samples exhibited a high sorption capacity for the antibiotic tetracycline.
