Özet:

 


Monolayer
films modified polycrystalline
gold electrode has
been fabricated by using self assembled monolayer method of 1,6-hexanedithiol and
1-hexanethiol
and
used for electro-catalytic oxidations of iron(II). A calibration curve was
obtained for Fe(II) in a wide concentration range from 5.00×10-8 mol.L−1
 to 3.85×10-5 mol.L−1
and detection limit of 1.6×10-8 mol.L−1
on
the Au-HDT electrode. Additionally, on the Au-HT electrode, the linear range from
1.00×10−8
mol.L−1
to 2.56×10−5
mol.L−1
and
detection limit of 3.20×10−8
mol.L−1
for the determination of Fe(II) were achieved. Validity of the method and
applicability of the electrodes are successfully tested by determination of
Fe(II) in real samples.
