This manuscript provides a focused, qualitative synthesis of smart nanoadsorbents (stimuli\u2010responsive and engineered nanoenabled sorbents) for EC removal, emphasizing how surface chemistry, porosity, and responsive switching (pH, redox, light, magnetic, thermal, and multistimuli) can improve selectivity, adsorption kinetics, and regeneration. Novelty lies in integrating mechanistic adsorption concepts with a commercialization\u2010oriented perspective: We compare reported systems qualitatively using practical readiness indicators (ease of separation and immobilization, reusability, fouling tolerance, secondary release risk, and anticipated cost and scale\u2010up constraints) rather than capacity values alone. Across the surveyed literature, composite architectures (nanomaterials integrated with polymers, membranes, bio\u2010supports, magnetic cores, or granulated matrices) consistently emerge as more deployable than free nanoparticles because they reduce aggregation and leaching while enabling continuous formats such as packed\u2010bed cartridges, coating layers, and hybrid filtration\u2010adsorption units. These insights support near\u2010term industrial applications in polishing steps for hospital and municipal wastewater, textile and pharmaceutical effluents, landfill leachates, and decentralized point\u2010of\u2010use devices, while highlighting remaining gaps in standardized testing, life\u2010cycle safety, and pilot\u2010scale
