This paper describes a novel electrochemical microbial biosensor based on Thiobacillus thioparus cells for sulfide detection. The morphology and electrochemical properties of the proposed biosensor were characterized by SEM and cyclic voltammetry, respectively. Working conditions of the microbial biosensor were optimized to obtain good electrochemical performances. Under the optimum conditions, analytical...
This paper describes a new electrochemical sensor based on reduced graphene sheets (RGSs) modified glassy carbon electrodes for rapid detection of sulfide. The morphology and electrochemical properties of the RGSs are characterized by atomic force microscopy and cyclic voltammetry. The effects of the scan rates and pH are investigated to evaluate the oxidation processes. Analytical performances of...
