abstract = "The phenol quantification using boron-doped nanocrystalline
diamond (BOND) from electroanalytical technique of square wave
voltammetry (SWV) is reported. BDND depositions were performed
using Hot Filament Chemical Vapor Deposition reactor, where it was
possible to grow films with statics substrate-holder (sample Si)
or with spinning substrate-holder (sample S2). The variation of
this growth parameter induced significant changes on the electrode
properties. For example, the electrode S2 presented smoothness
surface with low roughness in relation to that for electrode Si.
Besides, Raman spectra showed different features for both
electrodes that could be related to boron incorporation.
Electrochemical measurements also presented differences between
electrodes, showing the advantages of electrode 52, such as, rapid
charge transfer, large electrochemical area and excellent phenol
detection limit similar to 0.1 mg L(-1). The phenol standard
sample of 8.0 mg L(-1) was used to validate the application of
this electrode as a nanosensor. Its concentration calculated from
SWV using electrode S2 was 8.2 +/- 0.2 mg L(-1) while from Ion
Chromatograph it was 7.9 +/- 0.1 mg L(-1). These results
demonstrated the high potential of BOND electrodes for
electroanalytical applications.",
