Non-Commercial Agro Waste Product for the Removal of Acid Red114 using Ipomea carnea Stem Waste

Ipomea carnea stem waste treated using phosphoric acid (ICAC) has been identified as the low cost agro waste adsorbent for the removal of Acid Red-114 (AR-114) from the aqueous solution. The optimum condition adopted for dye removal was found to be pH 6, adsorbent dosage = 100 mg/L of solution and equilibrium time=240mins. Nearly 87% of the dye has been removed at a concentration of 20 mg/L. Pseudo Second order kinetic model has been obeyed. The adsorption isotherm data fitted well to Langmuir equation and the Q0. Value obtained to be 80.86 mg/L. The results achieved clearly indicate that the chosen adsorbent is found to be a promising material for the adsorption of AR-114.
