Carbon nanohorn electrochemical sensor for Cr(VI) in tap water

Overview

A carbon nanohorn-modified electrochemical sensor for Cr(VI) (hexavalent chromium) detection was developed and validated in tap water samples. The paper targets Cr(VI) specifically, not total chromium, preserving the critical speciation distinction.

Key numbers

• LOD, linear range, and Cr(VI) detection performance in full paper.
• Tap water validation: recovery experiments only, or actual Cr(VI) occurrence measurements? Confirm from full paper.

Methods (brief)

Carbon nanohorn-modified electrode for Cr(VI) electrochemical detection. Speciation-specific for Cr(VI). Tap water validation.

Implications

Certification: Cr(VI) is the regulated and toxicologically relevant chromium species. Method is relevant for analytical quality control in water and potentially food. Courses: Demonstrates Cr(VI)-specific electrochemical detection; reinforces the Cr(VI) vs total Cr distinction.
