Özet:

 

Cellulose acetate (CA) membranes were modified by  nano-silicon dioxide (n-SiO_2), and they were exposed to ultrasonic  waves at a frequency of 35 kHz. The effect of sonication on their water  sorption tendency and permeation capability was investigated. The  characterization of the membranes was done by FTIR and SEM analysis, and the  hydrophilic character of the membranes was deduced by swelling studies and  contact angle (CAn) measurements. Permeation studies of the membranes were  performed by using the diffusion method and theophylline was used as a model  chemical in the permeation studies. The results indicated that beside the  high hygroscopic property of n-SiO_2, the presence of n-SiO_2 in  CA membranes did not significantly improve their hydrophilicity; however,  when they were exposed to sonic waves, it was determined that the sonication  effectively enhanced their water sorption capacity and permeability.
