ABSTRACT A simple, sensitive and selective method is proposed for the determination of
copper (II) by adsorption-differential pulse stripping method. This method is based on the
selective accumulation of the complexes of Cu (II) with l-(2-pyridylazo)-2-Naphthol and then
reduction of the complex on a HMDE. The reduction current of the complex is about 0.0 V vs.
Ag/AgCl reference electrode at p8543146= 4.0. The influences of various experimental
parameters on the current peak were completely studied. The calibration graph was linear ...
