Pesticides are vital for protecting crops, but their overuse has led to serious environmental and health concerns. Carbon nanotubes (CNTs) have emerged as a promising tool for removing these pollutants due to their large surface area, strong adsorption capacity, and unique structural properties. Compared to activated carbon and graphene oxide, CNTs exhibit higher adsorption capacities and faster kinetics for pesticide removal due to their larger surface area, stronger π–π interactions, and tunable surface chemistry. This review highlights how CNTs—particularly when functionalized or combined with other materials—can effectively capture and detect pesticide residues. It also explores recent advances, challenges like toxicity and cost, and the need for safer, more sustainable applications. As research progresses, CNTs could play a key role in cleaner, more responsible agriculture.
