| 英文摘要 | An effective voltammetric method for determination of iron (Fe) in seawater was proposed based on the gold nanospheres (AuNSs)/electrochemically reduced graphene oxide (E-rGO) modified glassy carbon electrode (GCE). The AuNSs/E-rGO/GCE was prepared through a simple one-step electrodeposition method. E-rGO provides perfect conductivity, larger electrode surface, and more active sites for AuNSs which possess the ability to accelerate electron transfer and excellent electro-catalytic performance for the voltammetric determination of Fe3+. Benefiting from the synergistic effects of E-rGO and AuNSs, the AuNSs/E-rGO/GCE exhibited excellent performance for the voltammetric determination of Fe3+. Adsorptive stripping voltammetry was adopted for Fe3+ determination using the fabricated AuNSs/E-rGO/GCE with 1-(2-Pyridylazo)-2-naphthol as the complexing ligand. Under the optimal conditions, the AuNSs/E-rGO/GCE showed a limit of detection was 1.5 nM and linear range was 5 similar to 450 nM for Fe3+ determination. In addition, the AuNSs/E-rGO/GCE has been successfully applied to determine the total dissolved Fe in real seawater samples. |
