Structural and antibacterial properties of original vermiculite and acidified vermiculite with silver

Popis výsledku v původním jazyce

Original vermiculite and acidified vermiculites (formed at two different concentrations of hydrochloric acid solutions) were used as matrixes for precipitation and growth of silver nanoparticles. The precursor of silver for the Ag-vermiculites was silvernitrate solution. The vermiculite structure was studied by Infrared spectroscopy (IRS) and X-ray diffraction (XRD) analysis. The XRD patterns showed decrease in intensity of basal diffractions and disorder of vermiculite layered structure in dependenceon the concentration of acid solution used on the vermiculite. Morphology of vermiculite flakes was studied using the scanning electron microscope (SEM). Measurement of the specific surface area (SSA) showed significant increase at vermiculites after acid treatment. The content of silver determined by X-ray fluorescence (XRF) analysis was lower at acidified vermiculite samples than at original vermiculite. The antibacterial effect of prepared Ag-vermiculite materials was studied on the G
