Bulgarian natural expanded mineral obtained from Bentonit AD (deposit of “The BrokenMountain” for perlite mining, near the village of Vodenicharsko, municipality of Dzhebel) perlite, was loaded with silver (as Ag+ 2 and 5 wt% by the incipient wetness impregnation method), and as Ag0 using Tollen’s reagent (silver mirror reaction). DC arc-AES and XRD methods were used for Ag detection. Samples also were characterized with DR-IR and UV-VIS. The aim of this work was to obtain silver loaded catalyst for ozone decomposition.
Key words: perlite glass, Ag thin film, XRD, DR UV-VIS, IR spectroscopy, DC arc-AES method
