ue to unique physical and chemical properties, conjugated
polymers are applied in various areas of technology.
Synthesis of π-conjugated polymers and modification of
electrodes can be performed in several different ways,
the most popular of which are chemical, biochemical and
electrochemical methods. The electrochromic effects of
electrodes modified with electrochromic materials can be
evaluated inaddition toelectrochemical signals.Moreadvanced
overview of electrochromic materials and their application in
sensor design can be found in our recent review and in our
papers, which report the applicability of the electrochemically
deposited conjugated polymers (such as polyaniline (PANI)
and azo benzene with 3,4-ethylenedioxythiophene moieties)
and even inorganic materials (such as Prussian blue). In this
presentation, the performance of several electrochemical and
electrochromic sensors based on electrochemically deposited
π-π conjugated polymers (such as PANI, poly pyrrole and some
others) towards the determination of some heavy metal ions,
NH

and CO

will be reported. In present investigation, we have
simultaneously studied the electrochemical and electrochromic
performances of PANI film before and after the incubation of
the PANI/ITO electrode in the solution containing analyte. Two
potential steps based on pulse profile have been applied in
order to generate chronoamperometric and electro chromic
responses of the PANI/ITO electrodes in this investigation.
