Voltammetry of immobilized particles of cannabinoids
A new electrochemical method for the detection of cannabinoids in food products is proposed. The method is based on the voltammetry of microparticles at paraffin-impregnated graphite electrode. In square-wave voltammetry, in 0.1 M KNO3 at pH 7, the responses of delta-9-tetrahydrocannabinol, cannabinol and cannabidiol consist of a single peak with the maximum at 0.55 V 0.01 V. This peak is ascribed to electrooxidation of phenol group to phenoxy radical. In microparticles of hemp and marijuana cannabinoids can be detected in pure drug as well as in the mixture with foreign insoluble powders.
