A
sensitive electrochemical sensor was developed
for the analysis of dobutamine (Dob) using a glassy
carbon electrode modified with multi-walled carbon
nanotubes – boehmite nanoparticle composite (BNP-
MWNTs/GCE). Scanning electron microscopy (SEM)
was used for the characterization of synthesized BNPs
and the morphology of BNP-MWNTs on the surface of
GCE. Under the optimized experimental conditions, the
BNP-MWNTs/GCE exhibited higher peak current than
bare GCE due to synergetic effect of BNPs and MWCNTs
on the electrochemical oxidation of Dob. The effect of
various experimental parameters such as pH, scan rate,
accumulation time on the voltammetric response of Dob
was studied and optimized. Awide linear range from 0.005
to 1.0 µM with a low detection limit of 8.9 nM was found for
voltammetric quantification of Dob. The prepared sensor
exhibited the acceptable repeatability, high reproducibility
along with good stability which makes it appropriate
candidate for determination of Dob in pharmaceutical
preparations.
