ELECTROSYNTHESIS OF POLY(I,8-DIAMINONAPHTALENE) FILM IN AQUEOUS MEDIUM

Abstract

Poly(1,8-diaminonaphtalene) was electrosynthesized on platine in aqueous acid solution by potentiodynamic technique using acid chlohydric as an electrolyte support. Structure of the obtained polymer film was determined by Raman Spectroscopy. The Raman spectrum showedclearly the poly(I,8-DAN) structure according well to the literature. The sensing behavior of obtained modified electrode towards to Cu(II) ion was investigated by the change of film electroactivity via complexation copper-polymer after its immersion in the solution CuCl2. Theresults showed the presence of copper in the poly(I,8-DAN) matrix that can be detected by square wave voltammetry
