AI Article Synopsis
- The study focuses on detecting explosives like TNT in seawater using various types of electrodes, including graphene nanoribbons and graphite microparticles.
- Researchers found that few-layer graphene provides a slightly better signal for TNT compared to multilayer graphene, but graphite microparticles showed higher overall sensitivity.
- The detection limit for TNT in untreated seawater was established at 1 μg/mL.
Article Abstract
The detection of explosives in seawater is of great interest. We compared response single-, few-, and multilayer graphene nanoribbons and graphite microparticle-based electrodes toward the electrochemical reduction of 2,4,6-trinitrotoluene (TNT). We optimized parameters such as accumulation time, accumulation potential, and pH. We found that few-layer graphene exhibits about 20% enhanced signal for TNT after accumulation when compared to multilayer graphene nanoribbons. However, graphite microparticle-modified electrode provides higher sensitivity, and there was no significant difference in the performance of single-, few-, and multilayer graphene nanoribbons and graphite microparticles for the electrochemical detection of TNT. We established the limit of detection of TNT in untreated seawater at 1 μg/mL.
