Determination of lead(II), cadmium(II) and copper(II) in waste-water and soil extracts on mercury film screen-printed carbon electrodes sensor

Determination of lead(II), cadmium(II) and copper(II) in waste-water and soil extracts on mercury film screen-printed carbon electrodes sensor

A sensor incorporating a three electrodes configuration have been fabricated using low cost screen-printing technology. These electrodes couples with Square Wave Stripping Voltammetry (SWSV) has provided a convenient screening tool for on-site detection of trace levels of Pb(II), Cd(II) and Cu(II)....
