Sažetak
A self assembled monolayer of cysteamine (CA) was prepared on the surface of gold disc electrode and further modified with nitrilotriacetic acid (NTA). Modified Au/CA/NTA electrode was characterized with cyclic voltammetry and electrochemical impedance spectroscopy in presence of potassium hexacyanoferrate(II)/(III). Thus prepared electrode was tested for determination of Cu2+ with adsorption transfer stripping voltammetry. The binding of Cu2+ onto the modified electrode was successfully performed for a wide range of tested concentrations. Electrode response (Ip) was linearly proportional to -log c(Cu2+) with correlation coefficient R2 = 0.9767. The detection limit was M. The influence of interfering substances (Mg2+, Mn2+, Co2+ and Ni2+) was tested and it was found that Mg2+ does not interfere while Mn2+, Co2+ and Ni2+ show slight interference. Real-world testing of copper content in urine samples confirmed practical application of prepared sensor.
