A sensitive, simple and selective spectrofluorimetric method
has been proposed for determination Captopril (CPT) in pure form
and pharmaceutical preparations. This method depends on the
formation of complex between Captopril and Copper (II) at
pH=3.5.
The voltammetric behavior of captopril in presence of
copper ions was investigated by using adsorptive cathodic stripping
voltammetry at hanging mercury drop electrode.
