Abstract: Titanium dioxide nanoparticles were prepared from the cheap inorganic salt by the sol-gel method and used in the photocatalytic degradation of acetic acid in the aqueous solution. The experiment results show that the amount and heat-treated temperature of TiO2, the pH value and concentration of solution consid erably affect the process of the degradation. The influence of the coexistent in organic ions on the photodegration of acetic acid was investigated.

Key words: titanium dioxide nanoparticle, acetic acid, photocatalytic degradation
