Abstract

Background & objeftive: One of the most important environmental pollutants is color Compounds that are generally used in the textile, paper, cosmetics, food and leather industries, and their discharge into wastewater has harmful effects on the environment. The aim of this study is determination of the efficiency of ash and powder of ROSA DAMASCENA WASTEs in removal of Reactive Blue from aqueous solutions.Methods and Materials: In this experimental study, after the preparation of the powder and ash adsorbents of ROSA DAMASCENA WASTEs, the effects of various operation parameters such as pH (3-10), the initial concentration of dye (25, 50, 100 and 300 mg/L), contacttime (5-180 minutes) and adsorbent dose (0.5- 6 g/L) were studied. Finally the results were analyzed by KINETICS and isotherm modeling.ResultsIn this study, equilibrium time of powder and ash of ROSA DAMASCENA WASTEs Obtained 60 and 45 minutes respectively. The Maximum efficiencies of the powder and ash adsorbents were obtained 74 and 91 percent, respectively, at pH of 3, contacttime of equilibrium and adsorbent dosage of 4 g/L. isotherm studies matched with Freundlich isotherm models for both adsorbents. Kinetic equations better followed the pseudo-second of the model:.Conclusion: The results showed that Powder and ash of ROSA DAMASCENA WASTEs can be used as the effective, available and affordable adsorbents for removal of color pollutants from aqueous solutions.
