Enhanced voltammetric determination of metal ions by using a bismuthene-modified screen-printed electrode

A new bismuthene carbon-based screen-printed electrode (2D Bi exf -SPCE) was easily prepared, taking advantage of the strongest features of exfoliated layered bismuth (bismuthene) for metal ions detection by differential pulse anodic stripping voltammetry (DPASV). An exfoliated bismuth suspension wa...
