A Study of Degradation of Azo-dye in System of Alga and Bacteria;

To accomplish the optical storage in short wavelength band and improve the thermal stability of storage media, a new synthetic method for nanocomposite materials which are codoped by metallic nanoparticles azo-dye compound (MNPADC) with structure for coating is presented for the first time.

Photocatalytic degradation of 16 azo-dyes in TiO2 suspension and irradiated by a high pressure mercury lamp has been studied.

Study on aerobic biodegradability of acid azo dyestuffs;

The structure and properties of azo dyestuffs such as Sudan I, Sudan II, Sudan III and Sudan IV are introduced in brief.

The background of that some azo dyestuffs which are harmful to human body was prohibited from using by European Union is briefly introduced.
