                         nanocrystalline diamond (BDND) films in the electrochemical 
                         determination of nitrite was reported. The morphology and the 
                         structure modifications as function of the boron doping level 
                         increase were observed. Two different doping levels were 
                         considered. A BDND film with a doping level of 30.000 ppm and one 
                         another with a doping level of 10.000 ppm was used. The columnar 
                         growth for the 30.000 ppm BDND led to a higher surface roughness 
                         and also to a greater grain size when compared to that 10.000 ppm 
                         BDND. The Raman spectra shown higher sp 2-bonded carbon amount in 
                         grain boundary for the 10.000 ppm BDND film due to decrease of the 
                         grain size. The morphological and structural modifications of the 
                         BDND films were crucial for nitrite oxidation process. The 30.000 
                         ppm BDND electrode presented a better sensitivity to the nitrite 
                         oxidation and a lower detection limit (DL) on the {"}as-grown{"} 
                         condition, while the 10.000 ppm BDND electrode presented a better 
                         analytical sensitivity and a lower DL after the surface 
                         pre-treatment with hydrogen plasm.",
