and uranium. They are especially suitable for the analysis of ground, drinking,
sea, surface and cooling waters, in which the concentration of these elements is of
importance. The methods can, of course, also be used for the trace analysis in
other matrices.
Titanium is determined by adsorptive stripping voltammetry (AdSV) with mandelic
acid as complexing agent. The determination limit lies at 0.5 µg/L.
Also uranium is determined as chloranilic acid complex with adsorptive stripping
voltammetry. Here the determination limit lies in low-chloride media at 50 ng/L, in
seawater at 1 µg/L and in high-chloride media in a ppm range, after the chloride
has been removed by means of a sulphate-loaded ion exchanger.
