A square-wave voltammetric procedure for the electroanalytical determination of losartan
and triamterene in Britton-Robinson buffer (pH 3.0, 0.1 mol L-1) as a supporting electrolyte
containing 30 ng mL-1 of copper ions was developed. Opposite to the case of triamterene,
losartan can not be reduced at a mercury electrode alone, but a new peak appears at-0.25 V
in the presence of copper due to the formation of a complex between copper (II) and
losartan. An accumulation potential of-0.30 V during 80 s for the prior adsorption of ...
