Anodic Stripping Voltammetry: Trace Metal Analyzer (2D)

Anodic stripping voltammetry (ASV) is the workhorse electroanalytical technique for detecting trace heavy metals — cadmium, lead, copper — at parts-per-billion levels in water and soil samples. This 2D simulator runs the real two-step ASV protocol in a pannable, zoomable cell cross-section: a deposition phase electroplates a dilute mix of Cd²⁺, Pb²⁺ and Cu²⁺ onto a working electrode as visible atoms accumulate on its surface, then a stripping phase sweeps the potential positive while a live voltammogram traces out the sech²-shaped current peaks predicted by surface-wave electrochemistry — each metal stripping off, atom by atom, exactly as its own peak sweeps past. Adjustable sample concentration, deposition potential, deposition time and scan rate let you explore why under-depositing a metal makes ASV under-report it, and why faster scans give taller, sharper peaks.
