Effectiveness of Rosewater Waste in De-colorization of Reactive Blue 19 from Synthetic Textile Wastewater
Journal Title: Journal of Health Research in Community - Year 2016, Vol 1, Issue 4
Abstract
Introduction and Purpose: Discharge of the wastewater containing reactive dyes into water resources can have detrimental effects on the environment and to the human health due to their carcinogenic, mutagenic, and toxic nature. The present study was performed to evaluate the efficiency of rosewater waste in removal of reactive blue 19 dye from aqueous solutions. Methods: In this experimental study, the effects of various application parameters including pH (4-10), initial concentration of dye (25 and 50 mg/L), contact time (15-180 minutes), and adsorbent dosage (0.2-0.6 g/L) were examined. Results: Maximum capacity of rosewater waste was 5.16 mg/g (pH: 4, contact time: 180 minutes, and adsorbent dosage: 0.4 g/L). Additionally, the model demonstrated that the absorption was more congruent with Freundlich absorption model (R2=0.985) than Langmuir (R2=0.903). Conclusion: It is concluded that rosewater waste could effectively remove reactive blue 19 dye from aqueous solutions and textile industry effluent.
