Abstract
The potentiometrical analysis of Cu2+ using Nafion- modified electrode with Cu
complex with DPABA (Methyl 3,5-bis{bis-[(pyridin-2-yl)methyl]amino}methyl)benzoate)
incorporated, is described. Parameters and conditions such as the volume of 2% Nafion, pH,
and the concentration of Cu complex with DPABA and pH of medium were optimized.
Interference of Fe3+, Co2+ and Zn2+ with Cu2+ were examined. Calibration curve was linear in
the range of 1×10-7-5×10-5 mol/L. The detection limit was 7×10-8 mol/L. A response time of
the proposed electrode was 3 s.
