Sažetak
Voltammetry of selenium(+4)-rhodium(+3) system was studied in different electrolyte solutions
with special attention paid to possible application of the observed effects in selenite determination
at trace levels. Although the signals obtained from such mixtures can be more than
200 times higher than those resulting from simple selenium(+4) solutions without rhodium(+3)
added, it remains questionable how such results could be applied in practice. The main problem
is data treatment because (generally) current – concentration plot is not a straight line with
zero intercept. Additionally, its shape changes with the selenite concentration range. The problem
is illustrated taking as an example selenium(+4) determination in solutions of selenium(+6).
At present, results obtained in the system of interest seem to be important as phenomena and
possible indicators of some catalytic processes. Before their application in trace analysis the
answers to some general questions should be found.
