Abstract :

Pollutions from industrial wastewater contaminated color, is one of the main problems in environment. The purpose of this research is study of efficiency of active carbon modified by cupper oxide nanoparticles in remove of Tartazin from aqueous solution and determination its kinetic parameters. To gain maximum remove of color by modified carbon active, different parameters such as pH, buffer volume, temperature and absorbent contact time with sample was investigated for concentration of 10 mg/L. Tartrazin dye concentration in aqueous phase was determined by measurement of absorbance in 423 nm of wavelength.  The result showed that maximum removal was obtained in pH=7 and by using 0.05 gram of absorbent. R2 level obtained from Langmuir diagram shows that the maximum removal is according that and the capacity of active carbon is 35.61 mg/g. Study of the result shows that this nanoparticles is suitable as nanoabsorber for Tartazin removal from aqueous solution.
