Adsorptive Removal of Chlorinated Herbicides from Water Using Activated Carbon.In Pesticide Removal Methods from Waste Water: Proactive Approaches and Future Trends

Abstract

Water pollution due to the presence of chlorinated herbicides is a significant environmental concern. These toxic compounds are commonly used in agricultural practices and can contaminate water sources, posing severe health risks to humans and aquatic life. The adsorptive removal of chlorinated herbicides using activated carbon has shown promising results as an efficient and cost-effective treatment method. This research is dedicated to exploring the effectiveness of activated carbon obtained from diverse sources, encom passing agricultural waste and industrial byproducts, in serving as an adsorbent for elimi nating chlorinated herbicides from water. Batch experiments were conducted to assess the adsorption capability of the activated carbon and refine the process variables, including contact duration, initial herbicide concentration, and the quantity of adsorbent used. More over, the regeneration and reusability of the activated carbon were studied to explore its practical feasibility and economic viability. Thermal regeneration was found to restore the adsorption capacity of spent activated carbon effectively, making it suitable for multiple adsorption-desorption cycles. In addition, activated carbon exhibits remarkable adsorptive capabilities for the removal of chlorinated herbicides from water. Its low cost, widespread availability, and ease of regeneration make it a promising and sustainable solution for water treatment. This research contributes to the ongoing efforts in mitigating water pollution and underscores the significance of utilizing adsorption technology to safeguard both human health and the environment.
