Zusammenfassung:This paper reviews the most important sensor-based methods that are commonly utilized for detecting and measuring hydrogen sulfide (H 2 S) gas. It identifies a quite comprehensive overview related to the toxicity and hazardous effects of H 2 S gas from an individual and environmental health protection perspective. Furthermore, the description, classification, and comparison of the H 2 S gas sensing technologies are exhibited according to many criteria, such as sensing material, working principle, limit of detection, response time, operating range of gas concentrations, sensor stability, sensitivity, and selectivity toward H 2 S. Finally, it identifies the limitations of these sensors, suggests the most probably successful future technologies, and highlights the most promising approaches that have been developed for achieving inexpensive hydrogen sulfide gas sensors which could be employed in widespread miniaturized detectors in the real-world applications.
