چکیده انگلیسی
In this study, rapid electrochemical sensing systems for detection of arsenate by oxidation of l-cysteine are proposed. Three different sensing systems comprising of screen-printed electrode and standard electrodes were used for this study. The detector element i.e. l-cysteine was immobilized on the working electrodes of the transducers by in-situ polymerization of acylamide. The electrocatalytic oxidation of l-cysteine was performed by cyclic voltammentry and amperometry. All the systems presented linear response range up to 30 μg L−1 of arsenic. The sensors were able to estimate arsenic below 10 μg L−1 with a detection limit of 1.2–4.6 μg L−1.
