A PROCESS FOR REMOVAL OF CR (VI) FROM WATER USING LIMA BEAN HUSK DERIVED ADSORBENT

The present invention is related to a process for removal of CR (VI) from water using a lima bean husk-derived adsorbent. It involves the development and utilization of an adsorbent material derived from lima bean husks, a readily available agricultural byproduct. The method encompasses a series of processing steps, including drying, heating, washing, and sieving, resulting in an eco-friendly adsorbent material with a particle size range between 0.15 and 0.25 millimeters. Optimal operational conditions, such as flow rate, bed height, and pH, are established to maximize the adsorption process's efficiency. Under controlled conditions, the process effectively reduces the Cr (VI) concentration by more than 35 percent, rendering the treated water safe for consumption. This method provides an environmentally friendly and economically viable solution for addressing heavy metal contamination in water, with broad applications in water treatment and environmental remediation. Eco Adsorb embodies sustainability, resourcefulness, and the utilization of natural waste materials to address pressing environmental challenges.
