“…From the slope of the resulting plot and using Cottrell's equation, the diffusion coefficient of sulphite on the surface of N-HCSs/GCE was found to be equal to 4.45×10 -5 cm 2 s -1 . The value of D is comparable with values reported in some previous works (1.75×10 −5 [56], 2.5×10 −5 [57] and 1.2×10 −6 cm 2 s -1 [58]).…”

In this work, the glassy carbon electrode (GCE) surface was modified with nitrogen-doped hollow carbon spheres (N-HCSs) to achieve a new electrochemical sulphite sensor (N-HCSs/GCE) in water samples. The N-HCSs were explored for electrocatalytic behavior through voltammetric approaches using a routine three-electrode system. The findings revealed an admirable efficiency for modified electrodes towards sulphite oxidation, highlighting the effectiveness of our as-produced sulphite sensor. The differential pulse voltammetry was utilized under obtained optimal circumstances to study the as-developed sensor, the results of which underlined linear electrochemical current in relation to sulphite concentration, with dynamic range as wide as 1.0-100.0 μM and limit of detection as narrow as 0.35 μM. Moreover, N-HCSs/GCE had commendable practical applicability for sensing sulphite present in real specimens with voltammetric techniques.
