eng	Surface and electrochemical characterization of boron-doped diamond electrodes with different content of boron	This study is focused on comparison of lab-made boron doped diamond electrodes (BDDE) with different content of boron prepared by hot filaments chemical vapor deposition. These electrodes have been characterized to their surface and electrochemical properties. Surface characterizations were provided by Raman spectroscopy and scanning electron microscopy. Their physical, chemical and electrochemical properties were investigated by using electrochemical impedance spectroscopy and cyclic voltammetry with the reversible redox markers [Fe(CN)6]3-/4- and [Ru(NH3)6]3+/2+. From these characterizations, the important characteristics of the recorded curves as differences between anodic and cathodic peak potentials (ΔEp), anodic and cathodic peak heights (Ia, Ic), the ratios of Ia/Ic, etc., were found. At the end, all BDDEs were applied for determination of drug dantrolene, to compare obtained statistical parameters and to find out as behavior of these electrodes exhibits some trends in relation to the boron content. Results showed that with changing concentration of boron the electrochemical properties have been changing and proved that the content of boron in the diamond film significantly influences the electrochemical properties of the prepared electrode material.
