Chelating electrodes as taste sensor for the trace assessment of metal ions

Mostrar todas las versiones(2)

Impedance spectroscopy combined with principal component analysis allows the trace detection of metal ions. The detection system is based on two modified electrodes, each of them containing a chelating agent (pyrocatechol violet and a nitrilotriacetic derivative); as the chelator is able to capture...
