Název v původním jazyce

Electrochemical sensors for detection of acetylsalicylic acid

Popis výsledku v původním jazyce

Acetylsalicylic acid (AcSA), or aspirin, was introduced in the late 1890s and has been used to treat a variety of inflammatory conditions. The aim of this work was to suggest electrochemical sensor for acetylsalicylic detection. Primarily, we utilized square wave voltammetry (SWV) using both carbon paste electrode (CPE) and of graphite pencil electrode (GPE) as working ones to indirect determination of AcSA. The principle of indirect determination of AcSA bases in its hydrolysis on salicylic acid (SA),which is consequently detected. Thus, we optimized both determination of SA and conditions for AcSA hydrolysis and found out that the most suitable frequency, amplitude, step potential and the composition and pH of the supporting electrolyte for the determination of SA was 260 Hz, 50 mV, 10 mV and Britton-Robinson buffer (pH 1.81), respectively. The detection limit (S/N = 3) of the SA was 1.3 ng/ml. After that, we aimed on indirect determination of AcSA by SWV CPE. We tested the influenc
