Abstract: This study aims to find a suitable adsorbent for reducing the chemical content, specifically heavy metals like cadmium, in industrial effluent post-treatment. The project involves the identification and preparation of adsorbents, testing their efficacy through trial-and-error methods, and comparing results with and without the adsorbent. Orange peel and Delonix regia seeds were chosen as potential adsorbents. After preparation and activation, the adsorbents were tested with cadmium nitrate solutions, and their effectiveness was evaluated using UV spectrophotometer. The results indicate promising potential for both non-activated and activated adsorbents in reducing cadmium concentrations, laying the groundwork for further research into industrial wastewater treatment methods. This study offers a significant resource for policymakers, industry professionals, and environmentalists by offering a comprehensive view of the effluents of the manufacturing industry. It serves as a catalyst for sustainable industrial practices and the preservation of natural ecosystems.
