Abstract: 
This thesis describes the development and study of electroanalytical procedures for the
determination of trace metallic species in solution. Two major studies are included. In
the first study, a square wave stripping voltammetric procedure, utilizing a thin film
mercury electrode, was developed and optimized. The procedure was suitable for the
determination of Cd, Pb and Cu at the μg/L concentration level in natural water. The
second study included the construction and characterization of carbon paste electrodes
which were modified with zeolite molecular sieves. In conjunction with a medium
exchange procedure, electrode sensitivity to traces of Cu, Cd and Zn was achieved.
Furthermore, the interference effects from Co(II), Pb(II), Ni(II), Al(III), Cd(II),
Cu(II), Ag(1) and Hg(I1) on the Zn signals were studied. Most notably it was observed
that the interference was stronger for species, which had the higher coordination
number in solution. This suggests that electrode sensitivity and selectivity were partially
governed by the coordination numbers of the metallic species.
