Accordingly, it is essential to identify and quantify these phytosanitary products in the environment to reduce their occurrence and mitigate cumulative effects. A viable option for their adsorption and detection can be achieved using natural and sustainable raw materials, such as zeolites. In particular, natural zeolites are promising nanostructures for use in functional and sustainable detectors, and they may serve as low-cost adsorbent materials for hazardous agrochemical monitoring. This review compiles reported applications of natural, synthetic, and composite zeolites to improve the understanding of their potential for adsorption, and thus, detection of hazardous pesticides.

Elevated nitrate levels pose significant risks to both human health, such as methemoglobinemia (blue baby syndrome), and aquatic ecosystems through processes like eutrophication. The paper examines the potential of carbon composite-based electrocatalytic electrodes, particularly those incorporating reduced graphene oxide (rGO), for effectively removing nitrates from contaminated water. The review uniquely contributes by analyzing nitrate reduction mechanisms, rGO’s catalytic role, electrode fabrication challenges, operational stability, pilot-scale implementation, and pathways for industrial adoption of rGO-based electrocatalysts. The high surface area of these materials makes them interesting, have superior conductivity, and excellent catalytic properties, which enhance their ability to adsorb and reduce nitrate ions. It demonstrates how major advancements in carbon composites have improved the effectiveness and selectivity of nitrate reduction, demonstrating their potential for real-world applications. However, challenges remain, particularly about scalability, the durability of the materials, and the unwanted production of by-products like ammonia during the reduction process. The further research is necessary to overcome these challenges by focusing on the development of more stable, scalable, and cost-effective materials.
