Pyridoxine (vitamin B 6 , VB 6) was detected in pharmaceutical preparation and human urine samples by employing differential pulse voltammetry (DPV) at unmodified boron doped electrode. In Britton-Robinson buffer solution (BRBS) at pH 6 VB 6 provides well defined oxidation peak at around +1.05 V vs. Ag/AgCl (3M KCl). The influence of most of the interferents present in real samples, supporting electrolyte and DPV parameters were investigated. A VB 6 sensor with and linear range from 7 to 47 and a detection limit of 3.76 was obtain after optimization. Repeatability of the proposed procedure calculated after 7 measurements of 9 and 30 µM of VB 6 were 3.6 and 2.4 %, respectively. Proposed methodology was successfully applied for the determination of VB 6 in real samples, and from obtained results it can be concluded that proposed analytical procedure can be inexpensive alternative to the widely used separation methods.
