Application of screen-printed carbon electrode modified with lead in stripping analysis of Cd(II)
Original language description
In the work presented, a lead film electrode was prepared in situ on a screen-printed carbon support using a reversibly deposited mediator (Zn) and applied to the determination of Cd(II) by anodic stripping voltammetry. The electrochemical method for lead film formation is based on a co-deposition of a metal of interest (Pb), with a reversibly deposited zinc mediator, followed by oxidation of zinc, with additional deposition of lead at the appropriate potential. It serves to increase the density of lead particles, promoting lead film growth, and consequently helps to improve the electrochemical properties of the electrode. This was confirmed by microscopic and voltammetric studies. The obtained detection limit of Cd(II) is equal to 6.6 × 10-9 mol L-1 (-1.6 V for 180 s and then -0.95 V for 5 s). The presented procedure was successfully applied to cadmium determination in Bystrzyca River water samples.
