  Article:   UV-VIS AND RAMAN OBSERVATION OF EFFECT OF GAMMA RADIATION ON THE PAA-TiO2 MEMBRANES.

Authors:  M. TODICA.
 
       
         
  Abstract:  

The effect of gamma radiation on the physical properties of PAA-TiO2 membranes was investigated by UV-VIS and Raman methods. Before irradiation the UV absorbance of samples increases with the concentration of TiO2. Important modifications of this property appear after ╬│ irradiation. Some modifications of the Raman spectra can be observed after irradiation.

Keywords: PVA, TiO2, gamma irradiation.
