Abstract : The growing contamination of water sources by emerging pollutants, such as pesticide residues, poses significant environmental and health risks. Traditional water treatment methods often face challenges in terms of cost-effectiveness and regeneration. Smart adsorbents, offering self-healing properties, reusability, and environmental adaptability, provide a promising alternative. This review explores recent advancements in self-healing and stimuli-responsive adsorbents, such as thermo-responsive and pH-sensitive materials, for pesticide removal. Materials like bio-nanoporous carbon, magnetic nanoparticles, and metal-organic frameworks show outstanding performance due to their high surface area and tunable pore structures. Adsorption behaviour, often analysed through the Langmuir isotherm, suggests efficient monolayer adsorption and enhanced selectivity. Additionally, the potential for resource recovery and reuse of spent adsorbents adds to their environmental sustainability. However, challenges related to cost, scalability, and regeneration need addressing. Future research should focus on integrating intelligent water management systems with advanced technologies such as the Internet of Things and real-time monitoring applications to enhance regeneration processes and support sustainable water remediation.
