Abstract
Traces of vanadium(V) can be determined up to 21 ng/l by adsorptive st
ripping voltammetry using 2,5-dichloro-1,4-dihydroxy-3,6-benzoquinone
(chloranilic acid) as complex forming reagent. The complex is stable i
n a 0.1 mol/l acetate buffer (pH 4.6) solution and adsorbed at the ele
ctrode surface in a potential range between - 150 mV and - 400 mV. The
adsorption process is solved by alternating current (ac) voltammetric
measurements. The method is applied to different real samples.
