Abstract
An electrochemical sensor based on marine biomass shrimp shell-derived porous carbon (SSPC) modified glassy carbon electrode (GCE) was developed for the detection of hydroquinone (HQ) in this paper. The resultant SSPC was characterized by different methods including scanning electron microscopy and Fourier transform infrared spectroscopy. Brunauer-Emmett-Teller method was used to evaluate the pore structure and surface area of SSPC. The electrochemical behaviors of SSPC/GCE were explored by cyclic voltammetry and differential pulse voltammetry. The SSPC/GCE demonstrated linear response ranges of 5.0–25.0 μM and 25.0–1200.0 μM for HQ analysis with the limit of detection as 0.18 μM (S/N = 3). Additionally, the method had been successfully applied to determine HQ in real lake water sample, which provided potential applications in further sensing study.
