Removal of Heavy Metals from Water by Adsorbent Method

Abstract: This study investigates the removal of heavy metals from water using adsorbents, focusing on the effectiveness of various materials, their mechanisms of action, and factors influencing adsorption efficiency, aiming to develop sustainable and cost-effective water treatment solutions. Heavy metal contamination poses a significant threat to water resources and human health, necessitating effective removal strategies. This study explores the application of adsorption techniques for the removal of heavy metals from water, focusing on the characteristics and performance of different adsorbents. The research investigates the adsorption capacity, influencing factors like pH, temperature, and contact time, and the mechanisms of heavy metal removal by various adsorbents, including activated carbon, bio-adsorbents, and modified materials. The findings aim to provide insights into the development of sustainable and cost-effective water treatment technologies, emphasizing the importance of adsorbent selection and optimization for efficient heavy metal removal. Sustainability of good health depends upon the purity of water. However groundwater may be exposed towards to contamination by various anthropogenic activities such as agricultural, domestic and industrial. Groundwater quality problem are typically associated with high level of iron concentration in and Futala lake Nagpur. The normal drinking water contains permissible limit of iron concentration 0.3mg/l but the Groundwater contains 17mg/L and Futala Lake contains 1.16mg/L of iron concentration. In the present study Sugarcane Bagasse (SCB) and Coconut coir (COC) from agricultural waste have been selected as solid phase extractor for removal total iron. Sugarcane Bagasse, Coconut coir exhibits remarkable binding characteristics for removal total iron, so special interest was devoted for optimizing its uptake and studying its selectivity properties under static and dynamic conditions. The parameters such as effect of pH, adsorbent dosage, contact time, initial concentration, etc., were studied. Maximum removal of total iron was observed in the pH range of 4-5. The highest percentage removal of total iron was observed at Coconut coir (96%) compared than Sugarcane Bagasse (93%).
