Abstract

The research proposed is in relation to real-time detection of Sulphur ions within aqueous mediums, with the future potential of detection of Hydrogen Sulphide (H2S) in wastewater systems. Electrochemical Impedance Spectroscopy (EIS) is utilized alongside a novel interdigital capacitive sensor. The synthesis of graphene-based polymer composite thin films for Sulphur ion absorption are detailed. Sampled Sulphur measurements are conducted by using the presented thin-film coatings. The sensitivity curve obtained for a range of Sulphur concentrations from 0.5 ppm to 50 ppm, highlights the promising initial results, and strong potential for use within detection of H2S. The coating of Reduced Graphene Oxide (rGO) with silver nanoparticles (AgNPs) exhibits an enhanced sensitivity towards Sulphur ions. A portable IoT-based system is also presented for detection of Sulphur irrespective of time and place. This paper provides a detailed approach from conception to employment of the developed system.
