New voltammetric procedure for determination of thiamine in commercially available juices and pharmaceutical formulation using a lead film electrode

► Application of the lead film electrode for adsorptive stripping voltammetric determination of thiamine. ► Deposition of the lead film on a glassy carbon electrode. ► Accumulation by the adsorption of thiamine on the lead film electrode. ► Reduction of thiamine during the stripping step. ► Determination of thiamine in certified reference material, pharmaceutical formulation and commercially available juices.
