abstract = "In this paper, the influence of the doping level at boron doped
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.",
