Voltammetric determination of cocaine microparticles
A voltammetric method for the qualitative detection of cocaine powder traces on the solid substrates is described. A paraffin-impregnated graphite electrode is rubbed over the contaminated substrate and the microparticles of cocaine are mechanically transferred onto its surface. Using square-wave voltammetry in 1 M KNO3 at pH 2, the presence of cocaine is indicated by the peak at 0.36 ą 0.01 V vs Ag|AgCl|3 M KCl.
