Background and Objective: Acid dyes are synthetic organic compounds with complicated chemical structures which their treatment are difficult and costly. Discharchig of these dyes into the environmen causes harmful effects on ecosystem and water quality. In this study efficiency investigation of photo-fenton process in removal of acid green 20 dye from wastewater of textile industries was assessed.

Materials and Methods: Experimental study in the first half of 2015 was carried out in environmental health engineering research center, Kerman University of Medical Sciences. Factors which influence on removal including: pH, concentrations of H2O2 and Fe2+ ,light intensity of UV, the initial concentration of acid green 20 dye and contact time were investigated. Examinations under optimum removal conditions on real textile wastewater which its quality predetermined  were also carried out. Sampling and examinations were conducted according to standard methods for examination of water and wastewater 20th edition. Descriptive statistics was used for analysis of data.

Results: Optimum removal conditions were pH = 3 [H2O2]= 0.2 mMol,[ Fe2+]=40 mg/L, UV=30 watt , the initial concentration of acid green 20 dye= 25 mg/L and time= 10 minutes. Maximum removal values were 94.62 and 73 percent for synthetic solutions and real wastewater, respectively.

Conclusion: Photo-Fenton process is an effective way in removal of acid dyes and able to remove these dyes from wastewater with high efficiency.

Key words: Photo-fenton efficiency, Textile wastewater, Acid green 20

Funding: This research was funded by Kerman University of Medical Sciences.

Conflict of interest: None declared.

Ethical approval: The Ethics Committee of Kerman University of Medical Sciences approved the study.
