Abstract: Recently, graphene nanoribbons (GNR) have gained prominence for applications in high performance electrodes. However, this material might present some complications, such as restacking formation, lower electron mobility due to oxygen-containing functionalities and non-reversible structural damages related to oxidation processes, decreasing GNR response. Several papers sought to minimize this limitation, but the most part use high cost materials, rendering ineffective or hard the application of this device. Les… Show more

“…Diphenyl thiocarbazone is a well-known organic chelating agent that can form complexes with lead ions at appropriate pH and is usually used for spectroscopy detection of several kinds of heavy metal ions. 28,29 Chemically modified carbon paste electrodes (CPE) are easy to be fabricated with low cost. 30,31 In this work, the bismuth oxide and the chelating agent diphenyl thiocarbazone were mixed with carbon powder to prepare an ultrasensitive CPE for lead detection.…”
