• Abstract:

  Hydrogen sulfide gases emit an unpleasant, toxic, corrosive and extremely volatile odor for both living organisms and the environment. One of the major challenges encountered in hydrogen sulfide detection has been to offer a fast, highly sensitive and affordable technique for monitoring these toxic gases. This gas is extremely harmful to both living organisms and the environment and, depending on its concentrations, can result in chronic diseases, worsen pre-existing conditions and, in more severe cases, result in death within minutes of exposure. Hydrogen Sulfide can be found in oil and gas extraction platforms, coal manufacturing, among others. Thus, this systematic review seeks to present specific studies to identify this gas through experimental analyses, simulations and computational calculations. For this, the search for articles was performed using four search platforms, SienceDirect, PubMed, IEEE Xplore and Scopus. There were no exclusion criteria regarding the year of publication. Of the 32 articles selected, only eight (8) were used to prepare this review. Taking into account this low number of selected articles, it is possible to affirm that it is necessary to develop more research involving the study, design, manufacture and use of prototypes for the monitoring of toxic gases.
