Heavy metal ions present in the groundwater are toxic pollutants which contaminated of water is a world-wide environmental problem. This paper studies that an attempt made to adsorption kinetics of Indigo carmine dye from dye effluents onto activated carbon modified with metal chlorides is keen interest. The results show that activated carbon modified with metal chlorides such as FeCl2, SrCl2, and BaCl2 can be used as effective adsorbents for the removal Indigo carmine dye from dye effluents was observed. The kinetics of indigo carmine dye was adsorbed onto activated carbon modified metal chlorides were analyzed using pseudo-first order and pseudo-second order. Results were found to follow pseudo-second order equation.
