Název v původním jazyce

Stability of silver and copper on clay minerals at water environment and their antibacterial activity

Popis výsledku v původním jazyce

The present work is focused on the study of copper and silver stability on montmorillonite (MT) and vermiculite (VT) substrate in an aqueous environment and their antibacterial effect. Clay minerals MT and VT were saturated with silver and copper cationsin two different concentrations of the aqueous solutions of their nitrate salts. The structural changes of MT and VT after cations exchange were characterized by X-ray diffraction analysis. Elemental analysis showed that VT in comparison with MT contained higher amount of silver and copper while both clay minerals exhibited higher content of silver than of copper. Elements released into the water were quantitatively determined using atomic emission spectroscopy with inductively coupled plasma and atomic absorption spectrometry. The results yielded the finding that both silver and copper are sufficiently stably anchored on MT and VT matrices. The maximum percentage of released silver was 2.17 % from MT and 1.44 % from VT samples and rel
