Abstract
A cost-effective adsorbent was synthesized from Eichhornia Crassipes using phosphoric acid as an activating agent and it was applied for the decolourization of the Textile dyeing industry’s effluent (TDE). Physical, chemical and morphologic characteristics were investigated using characterization studies, BET and XRD techniques. Batch experiments were performed to determine the optimum dosage, temperature, time and pH. The ideal conditions for treating TDE were found to be 30 °C, 1 g/L dose, 90 min, and pH 7. Maximum decolourization of 92%, reduction of COD and BOD were found to be 66.77% and 83.94% respectively with 50 T TDE. As a result, the aquatic weed Eichhornia crassipes can be employed as an efficient adsorbent to remove dye from wastewater.
