Chitin-Functionalized Carbon Nanofiber-Based Electrochemical Sensor for Rapid and Sensitive Detection of 4‑Methylaminophenol in Aquatic Ecosystems.

ABSTRACT: 4-Methylaminophenol (4-MAP), commonly used in hair dye and photography industries, has a major undesirable ecological effect owing to its toxicity, persistence, and bioaccumulation in aquatic environments. Even at low concentrations, 4-MAP poses a threat to aquatic life and human health, and therefore accurate detection is essential as an environmental indicator. Nevertheless, the current approaches are either insensitive enough or too complicated to be applied regularly. In this work, we fabricated a chitin-functionalized carbon nanofiber composite (chitin/f-CNF) using ultrasonication technique and characterized using XRD, FT-IR, Raman, FE-SEM, EDX, elemental mapping, and HR-TEM analyses. The composite was applied to modify a glassy carbon electrode (GCE) and employed in the electrochemic
