Anodic stripping voltammetry.(short question with jeadings)
Accepted Answer
Anodic stripping voltammetry (ASV) is an electroanalytical technique used to determine the concentration of trace metals in a sample. It involves two steps:
1. Electrodeposition: The analyte is deposited onto a working electrode (usually a mercury electrode) by applying a negative potential. This reduces the metal ions in the solution to their elemental form, which then accumulates on the electrode surface.
2. Anodic Stripping: The potential is then scanned in a positive direction, causing the deposited metal to oxidize and redissolve into the solution. The current generated during this oxidation process is measured and is proportional to the amount of metal deposited on the electrode, hence the concentration in the original sample.
