Application of 1,6-hexanedithiol and 1-hexanethiol self-assembled monolayers on polycrystalline gold electrode for determination of Fe(II) using square wave voltammetry

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 .
