- Аннотация: The present paper describes an electroanalytical application of an activated carbositall electrode (ACSE) for the detection of purine nucleobases (adenine and guanine) and their derivatives by sequential injection-adsorptive stripping voltammetric approach (SI-AdSVA). It was found that ACSE characterized by significant electrocatalytic and adsorptive abilities toward investigated compounds over a wide pH range, good stability and reproducibility under the fixed hydrodynamic conditions. Utilizing on-line adsorption accumulation of an analyte during 120 s, the limit of detection (S/N = 3σ) was achieved down to 8 ng/mL (50 nM) and 10 ng/mL (75 nM) for guanine and adenine, respectively. It was demonstrated that the proposed SI-AdSVA method could be efficiently used for the routine analysis of real samples with satisfactory results.
