Background: Reactive dyes have extensively been used in textile industries, the effluence of the waste containing such dyes into water resources can pose hazardous effects on the environment and to the human health because of their carcinogenic, mutagenic, allergenic and toxic nature. The present research was performed to study the efficiency of residues of Rosa Damasena powder in removing Reactive red 198 dye from aqueous solutions.

Methods: In the present experimental study, effects of various operating parameters such as pH (4-10), initial concentration of dye (25 and 50 mg/L), contact time (15-180 mines) and adsorbent dosage (0.2-0.6 g/L) were investigated.

Results: Result showed that maximum adsorption capacity of the residues of Rosa Damasena powder was 5.19 mg/g at pH 4, contact time of 120 min and adsorbent dosage of 0.4 g/L. Besides, the equilibrium data were also fitted into the Langmuir and Freundlich equilibrium isotherm models which the data better fitted with Freundlich (R2=0.913) model than Langmuir's (R2=0.825).

Conclusion: According to results of the present study, it was found that residues of Rosa damasena powder has a high capacity to remove Reactive red 198 dye from aqueous solutions and textile industry wastewater.

Keywords: Reactive red 198, Surface adsorption, Natural absorbent, residues of Rosa Damasena powder.
