This work describes the electrochemical deposition of poly(cobalt(II)-tetraaminophthalocyanine) (poly(CoIITAPc)) film onto a multi walled carbon nanotubes (MWNT) modified glassy carbon (GC) electrode (designated as poly(CoIITAPc)-MWNT-GC electrode) by cyclic voltammetric method and the effectiveness poly(CoIITAPc)-MWNT-GC electrode towards electrocatalytic oxidation of hydroxylamine. Cyclic voltammograms recorded during electropolymerization of cobalt(II) tetraaminophthalocyanine (CoIITAPc) indicated that good adherent layer of poly(CoIITAPc) was incorporated on to the surface of MWNT/GC electrode. The electrochemical detection of hydroxylamine was studied by amperometry at the new poly(CoIITAPc)-MWNT-GC electrode. The modified electrode exhibited good catalytic performance for the electrochemical oxidation of hydroxylamine with an anodic potential of 0.2 V, linear concentration range from 1.7 mmol/L to 0.20 mmol/Land a detection limit of 0.33 mmol/L.
