Title: | Graphene-based electrochemical sensor for detection of 2,4,6-trinitrotoluene (TNT) in seawater: the comparison of single-, few-, and multilayer graphene nanoribbons and graphite microparticles | Authors: | Goh, Madeline Shuhua Pumera, Martin |
Keywords: | DRNTU::Engineering::Materials::Nanostructured materials | Issue Date: | 2010 | Source: | Goh, M. S., & Pumera, M. (2011). Graphene-based electrochemical sensor for detection of 2,4,6-trinitrotoluene (TNT) in seawater: the comparison of single-, few-, and multilayer graphene nanoribbons and graphite microparticles. Analytical and Bioanalytical Chemistry, 399(1), 127-131. | Series/Report no.: | Analytical and bioanalytical chemistry | 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. | URI: | https://hdl.handle.net/10356/95731 http://hdl.handle.net/10220/10025 |
