Fabrication of 2, 5 bis (4-methyl piperaz-1yl-methyl) 1-4- hydroquinone modified Wax Impregnated Graphite Electrode (WIGE) was used for highly selective, sensitive accumulation and detection of copper ions in real samples. Techniques like cyclic voltammetry(CV) and electrochemical impedance spectroscopy(EIS) were used to investigate ligand modified WIGE and the ion permeation through it. The electrochemical behavior of copper ions on ligand modified WIGE was studied through scan rate effect and pH study. The results indicated that CV peak currents have a linear relationship with concentration in the range of 0.05mM to 5mM, with a correlation coefficient of 0.983. The detection limit could be estimated 5 x 10-5M for Cu(II) ion by cyclic voltammetric method. The interference study was performed for equal molar concentrations of Cu(II), Pb(II) and Hg(II) ions on ligand modified WIGE.
