Bu çalışmada, kurşun oksit-grafen (PbO-G) nanokompozitlerinin
Au elektrot yüzeyinde katodik elektrodepozisyonu; yeni bir elektrokimyasal
metot kullanılarak Pb⁺² ve grafen oksit ihtiva eden aynı çözelti içerisinde,
sabit tek bir potansiyelde gerçekleştirildi. Elde edilen kompozit malzemenin
morfolojik ve yapısal özelliklerini analiz etmek için XRD, XPS, SEM ve EDS
spektroskopisi teknikleri kullanıldı. PbO-G nanokompoziti askorbik asit (AA) ile
dopaminin (DA) eşzamanlı elektrokimyasal tespiti için çıplak Au ve PbO-modifiye
edilmiş Au elektrotlardan daha yüksek bir akım yoğunluğu ve daha düşük
oksidasyon potansiyeli gösterdi. Ayrıca DA’in PbO-G elektrot yüzeyinde
amperometrik tayini incelendi ve 0.5 µM
ile 100 µM arasındaki doğrusal aralıkta tayin sınırı (sinyal/gürültü oranı=3 için) 0.001±0.00028 µM olarak hesaplandı. PbO-G
nanokompozit modifiye elektrot, AA varlığında DA’in elektrokimyasal tespiti ve
amperometrik tayini için yeni, basit ve düşük maliyetli bir analiz yöntemi sağlamaktadır.

Simultaneous Electrochemical Detection of Ascorbic Acid and Dopamine on PbO-Graphene Electrode

Öz

In this study, cathodic electrodeposition of lead oxide-graphene (PbO-G)
nanocomposites on Au electrode surface was carried out by a new one-pot
electrochemical method in the same solution containing Pb⁺² and
graphene oxide. XRD, XPS, SEM, and EDS spectroscopy techniques were employed to
analyze the morphological and structural characteristics of the composite
materials. For
simultaneous electrochemical detection of ascorbic acid (AA) and dopamine (DA),
the PbO-G nanocomposite exhibited a higher current density and lower oxidation
potential than the bare Au and PbO-modified Au electrodes. Also, the amperometric detection of dopamine on PbO-G electrode surface was
investigated and the limit of detection was estimated as 0.001 µM
in the linear range from 0.5 µM to 100
µM (at a signal-to-noise ratio of 3.0). This PbO-G nanocomposite-modified electrode
provided a novel, simple, and low-cost route for the electrochemical detection
and amperometric sensing of DA in the presence of AA.
