26-26 RECICLAREA DEŞEURILOR PROVENITE DE LA BATERIILE AUTO ÎN STICLE PE BAZĂ DE PLUMB


THE RECICLYNG OF THE WASTES PROVIDED
OF AUTO BATTERIES IN LEAD GLASSES
The purpose of this paper was i) to obtained the lead glasses with the
xPb∙(100-x)PbO2 composition where x = 0-15mol % Pb by melt quenching
method and ii) to characterized of the structural and optical properties of the
obtained glasses by investigations of FTIR and UV-VIS spectroscopy in order
to possible applications in the auto battery recycling.
FTIR data show that the accommodation of the host glass with excess
of metallic lead was possible by the conversion of some [PbO6] octahedral
structural units into [PbOn] structural units where n=3 and 4. Then, the increase
of the metallic lead high content in the matrix network will produce to the
deficiency of non-bridging oxygen’s and the formation of UV-VIS bands in
region centred at about 300nm which can be attributed to the electronic
transitions of the lead ions.
