Abstract :Monolayer films modified polycrystalline gold electrode has been fabricated by using self assembled monolayer method of 1,6-hexanedithiol and 1-hexanethiol and used for electro-catalytic oxidations of ironinsert ignore into journalissuearticles values(II);. A calibration curve was obtained for Feinsert ignore into journalissuearticles values(II); in a wide concentration range from 5.00×10 -8 mol.L − 1  to 3.85×10 -5 mol.L − 1 and detection limit of 1.6×10 -8 mol.L − 1 on the Au-HDT electrode. Additionally, on the Au-HT electrode, the linear range from 1.00×10 − 8 mol.L − 1 to 2.56×10 − 5 mol.L − 1 and detection limit of 3.20×10 − 8 mol.L − 1 for the determination of Feinsert ignore into journalissuearticles values(II); were achieved. Validity of the method and applicability of the electrodes are successfully tested by determination of Feinsert ignore into journalissuearticles values(II); in real samples .
