Effectiveness of Natural Adsorbents for Dye Removal in Wastewater: A Comparative Study

Water is vital for life, plays a crucial role in the ecosystem, and is highly sought after due to its limited availability. The waste water from dye industries poses significant environmental challenges due to the presence of high concentrations of synthetic dyes and chemicals, which can adversely affect aquatic ecosystems and human health. This project investigates the effectiveness of three adsorbents, such as the banana trunk powder, biochar and rice husk ash, for removing dyes from waste water. The selection of these adsorbents was based on their affordability, accessibility and possible adsorption abilities. The efficiency of these adsorbents is evaluated via their adsorption onto activated carbon, which is produced through the chemical activation of these adsorbents in a hot air oven. Tests for pH, turbidity and hardness were used to assess the purity of the treated water. The study aims to evaluate how effectively three adsorbents, banana trunk powder, biochar, and rice husk ash, remove dyes and to identify the most efficient adsorbent for achieving optimal performance.
