The use of Boron Doped Diamond Electrode for Determination of 5-hydroxyindoleacetic Acid

Original language description

A new method for voltammetric determination of clinical biomarker 5-hydroxyindoleaceticnacid (HIAA) at the boron-doped diamond electrode (BDDE) was developed. Anodically andncathodically pretreated BDDEs were tested in the pH ranges from 1 to 12, pre-treatment atn+2.0V/60 s, and pH 3 was found to be the optimum.nThe optimum square wave voltammetry (SWV) parameters were: f = 12 Hz, amplitude 60nmV, and potential step 4 mV. SWV concentration dependency was constructed in the rangenfrom 0.1 to 100 μmol L−1, limits of determination and detection were 0.3 and 0.1 μmol L−1,nrespectively. HIAA oxidation electrode process at BDDE was diffusion-controlled, asnuncovered by cyclic voltammetry. Interestingly, HIAA peak potential was constant in variousnranges of pH, indicating a non-Nernstian behavior at the BDDE, in contrast to a previouslynpublished electrooxidation mechanism consisting of a coupled H+/e− transfer.
