چکیده
A new grafted polymer electrode self modified with activated carbon (GPESMAC) was fabricated and electrochemical characterization by cyclic voltammetric analysis. The polystyrene was used as polymer grafted with acrylonitrile as a monomer and activated carbon as improvement material using gamma irradiation to produce a new copolymer. The redox process of K3Fe(CN)6 during cyclic voltammetry was studied with the new working electrode (GPESMAC) by cyclic voltammetric analysis. The physical properties of these electrodes have high hardness, insolubility, and stability at different high temperatures. Also, the sensitivity under conditions of cyclic voltammetry is significantly dependent on different scan rate and concentrations. The GPESMAC was characterized by surface analytical methods including SEM and AFM. Interestingly, the redox reaction of Fe(III) solution using GPESMAC remained constant even after 15 cycles. It is therefore evident that the GPESMAC possesses some degree of stability. The potential use of the grafted polymer as a useful electrode material is therefore clearly evident. It is through the study of applications in quantitative and qualitative analysis proved that the conductivity of grafted polymer with activated carbon is highly efficient and stability compared with the commercial solid electrodes and modified by mechanical means or by evaporating the solvent, such as glassy carbon electrode. On the other hand an enhancement of redox current peaks and high detection limits effective species such as Fe(II)/Fe(III) was studied.
