“…A new approach for the rapid detection of sulfide was reported by Xiaodong et al. via GCE modified with hemin‐functionalized reduced graphene oxide (GCE/hemin‐rGO) [77] . The fabricated GCE/hemin‐rGO was successfully employed for the selective amperometric determination of sulfide at a working potential of +0.05 V (vs Ag/AgCl) based on the reaction between sulfide and the active site of Fe 3+ in hemin.…”

Due to their potential applications in industry and potent toxicity to the environment, sulfides and their detection have attracted the attention of researchers. To date, a large number of controlled‐potential techniques for electrochemical sulfide sensors have been developed, thanks to their simplicity, reasonable limit of detection (LOD), and good selectivity. Different researchers have applied different strategies for developing selective and sensitive sulfide sensors. However, there has been no systematic review on controlled‐potential techniques for sulfide sensing. In light of this absence, the main aim of this review article is to summarize various strategies for detecting sulfide in different media. The efficiencies of the developed sulfide sensors for detecting sulfide in its various forms are determined, and the essential parameters, including sensing strategies, working electrodes, detection media, pH, LOD, sensitivity, and linear detection range, are emphasized in particular. Future research in this area is also recommended. It is expected that this review will act as a basis for further research on the fabrication of sulfide sensors for practical applications.

“…Sulfur (S 2-), the reduced form of sulfur compounds (such as HSand H 2 S), is generally formed in waste water by anaerobic bacteria on organic matter [1]. It has been reported that over 50 ppm of sulfide concentration was declared as to be high toxicity which is harmful to the human health [2]. Beside toxic effects, the studies in the last decade approved that H 2 S acts a significant role in extending of the postharvest shelf life of many herbal foods such as vegetables and fruits [2,3,4].…”

Beside toxic effects, the studies in the last decade approved that H 2 S acts a significant role in extending of the postharvest shelf life of many herbal foods such as vegetables and fruits [2,3,4]. Also, sulfide salts have been commonly used to control the toxic metal levels in environment, because most of metal sulfides are insoluble and they are easily found as precipitated in waste waters [1].…”

In this study, pyrocatechol violet (Pcv) is proposed for the first time as an efficient electrocatalyst for oxidation of sulfide and flow injection analysis (FIA) of sulfide. A graphite pencil electrode (GPE) was modified with Pcv via immersion of the GPE into 0.01 M Pcv solution for 15 min. Cyclic voltammograms (CVs) demonstrated that Pcv/GPE exhibits a good electrocatalytic performance due to shift in the potential from +400 at bare GPE to +70 mV at Pcv/GPE and obtaining an enhancement in the peak current compared with the bare GPE. A linear range between 0.25 and 250 µM sulfide with a detection limit of 0.07 µM was obtained from the recorded current-time curves in Flow Injection Analysis (FIA) of sulfide. Sulfide in water samples was also successfully determined using the proposed FI amperometric methods.

“…Graphene (GR), a 2D nanomaterial with single layer sp 2 hybridized carbon atoms, has been widely applied to modify electrode for its large surface area, excellent electrical conductivity, low cost, outstanding mobility charge carriers, and fast electron transfer rate. 21,22 The graphene modified electrode shows great promise for the analysis of many kinds of material such as folic acid, 23 baicalein, 24 dopamine, 25 hydrogen peroxide, 26 and environmental samples 27 etc. Compared to the uncontinuous graphene oxide, reduced graphene oxide on the GCE surface has better electron transfer ability.…”

A sensitive electroanalytical method for determination of kojic acid has been investigated on the basis of the enhanced electrochemical response at poly(L-arginine)-electrochemically reduced graphene oxide modified glassy carbon electrode fabricated by cyclic voltammetry. The glassy carbon electrode, poly(L-arginine) modified glassy carbon electrode, electrochemically reduced graphene oxide modified glassy carbon electrode, and poly(L-arginine)electrochemically reduced graphene oxide modified glassy carbon electrode were characterized by electrochemical impedance spectroscopy. The electrochemical behaviors of kojic acid were studied by cyclic voltammetry and differential pulse voltammetry in detail. Under optimal experiment conditions, the sensitive oxidation peak of kojic acid was appeared at 1.07 V and the calibration curves for kojic acid were obtained in the range of 7.50×10-7 − 1.00×10-4 mol L-1 and 1.00×10-9 − 5.00×10-7 mol L −1 with a detection limit of 1.0×10-9 mol L-1 (at an S/N of 3). This method has been applied to the determination of kojic acid in the rice wine samples with satisfactory results
