Behaviour of aniline when voltametrically electropolymerized in the presence of Ni²⁺, Co²⁺, and Cu²⁺ cations has been studies 0.1 mol ·L^-1 aniline in the presence of 0.01 mol·L^-1 copper(II), nickel(II), and cobalt(II) ions and of three inorganic acids: HCl, HNO₃, and H₂SO₄, was used. Aniline shows that polymerizes in all strong acids and metal ions selected, the reversibility and clarity of the redox processes in the presence of metal ions, indicate that the most accurate conditions for electrosynthesizing polyaniline (Pani) was CuCl₂ in 1.0 M HCl; Ni(NO₃)₂ in 1.0 M HNO₃ and in HNO₃ 1.0 M Co(NO₃)₂. In all cases, similar voltamograms were obtained and polymer growing changes according to the metal ion used. For Co(II), is more favorable in the following order: H₂SO₄ > HCl > HNO₃. For Ni(II) is H₂SO₄ > HCl @ HNO₃, and for Cu(II) is H₂SO₄ > HCl @ HNO₃. The aim of this work is to study the effects of metal ions on aniline and their electropolymerization in acid media
