عنوان انگلیسی Electro-determination of Chromium Ions based on Carbon Paste Electrode Decorated with Highly Nitrogen-Sulfur-Doped Graphene Oxide
چکیده انگلیسی مقاله This research has successfully created a carbon paste electrode that has been modified with nitrogen-sulfur-doped graphene oxide, allowing for the accurate detection of chromium ions in aqueous solutions. The surface morphology of the modifier was investigated by FT-IR and SEM.  Through the use of anodic stripping differential pulse voltammetry, the electrochemical response of the modified carbon paste electrode to chromium ions has been analyzed and shown to exhibit an excellent electro-oxidation response when exposed to chromium ions. The linear dynamic range of chromium analysis produced a remarkable sensitivity of 0.1986 between 0.01 and 10 nM, with a sensitivity of 0.2048 between 10 and 125 nM. The detection limit was found to be 4.58 pico-molar. In a real sample, the electrode was able to measure chrome (VI) with results comparable to other techniques used in measuring chrome (VI). This achievement highlights the possibilities of utilizing innovative technology to create solutions that can address real-world problems.
