Abstract
Trace metals in bound forms within an optimal concentration window play a vital role in maintaining ecological balance. But when present as free ions, even at low concentrations, they are toxic, resulting in catastrophic changes like altering the biota in a niche. Rapid and sensitive measurement of these trace metals in contaminated coastal seawater is essential to monitor trace element contamination. In this talk, we use electrochemical deposition to modify the surface moieties of the carbon fiber microelectrode in a controlled manner to enhance sensitivity towards trace metals to detect them in the environment/ecosystems. Our modifications offer a significant improvement in sensitivity compared to existing methods.
