Abstract: Electrochemical sensors sensitive to aniline were prepared by matrix polymerization and studied. Polyaniline electrodes under investigation were synthesized by electrochemical polymerization of 0.1 M aniline in 1.0 M aqueous HCl and 1.0 M NaCl, as well as in 1.0 M NaClO4 in CH3CN either in potentiostatic mode at 0.6, 0.9, and 1.2 V relative to Ag-AgCl or by potential cycling between -0.2 and 0.8 V; -0.2 and 1.1 V relative to Ag-AgCl. It was found that electropolymerization under conditions of maximal polymer film density results in a significant increase in selectivity. The regularities in sensor functioning were studied under various test conditions
