Abstract

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.
