Detection of Selenium and Nickel Metal Ion in Water Using Mn3O4-CnO4Modified Electrode

Andrew Miller

The Mn3O4-Cn electrode's design and application for simultaneous detection of selenium and nickel in water. The developed electrode can be utilised as a portable electrochemical device to assess Se (IV) and Ni (II) levels in affected areas. With 0.1 M Phosphate Buffer Saline (PBS) and 5 mM Fe (CN)6 as the supporting electrolyte, the best results are obtained. The number of cycle repetitions and the scan rate have a significant impact on peak shape and intensity. Because heavy metals are nonbiodegradable, they pose a significant risk to species in the environment. Metal ions in diverse mediums are analysed using systematic processes at a number of research laboratories. Atomic absorption spectrometry, atomic fluorescence spectrometry, high-pressure liquid chromatography, gas chromatography, and flow injection analysis are all part of this process. These methods each have their own set of disadvantages. Low cost, on-site availability, stability, reproducibility, accuracy, and detection of multiple ions are all advantages of electrochemical detection of metal ions.
