Voltammetric determination of dopamine using modified glassy carbon electrode by electrografting of catechol
Main Article Content
Abstract
By means of cyclic voltammetry as a diagnostic technique, the present study tried to describe behavior of dopamine (DP) at the bare and catechol electrografted glassy carbon electrode (CA/GCE). The results indicated that the CA/GCE exhibits high electrocatalytic activity toward DP. The DP cyclic voltammetry being at the CA/GCE showed two linear calibration ranges between 5.0 - 100 and 100 - 750 μM with a detection limit of 0.86 μM. For 6 DP replicate measurements (50 μM), R.S.D (the relative standard deviation) was 2.7 %. This method was successfully used for the determination of DP in serum samples.
