Simultaneous Determination of Ascorbic Acid, Dopamine and Uric Acid with Chitosan‐Graphene Modified Electrode
Abstract
Chitosan functionalized graphene was synthesized by a together‐blending and in situ chemical reduction method. UV‐vis, FT‐IR, Raman and SEM techniques were used to study the molecular structure and morphology of the resulting composite. The chitosan‐graphene modified glassy carbon electrode showed high electrocatalytic activity towards oxidations of ascorbic acid (AA), dopamine (DA) and uric acid (UA). By using the differential pulse voltammetry (DPV) as the analytical technique the calibration curves for AA, DA and UA, determined simultaneously, were found linear with a concentration range of 50–1200 μM, 1.0–24 μM and 2.0–45 μM, respectively.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
