Colorimetric sensor for As3+ detection in water

Overview

A colorimetric sensor for detection of As3+ (arsenite) in water was developed. The paper focuses on method development for drinking water applications. No food matrix samples are reported. The sensor detects As(III), a specific inorganic arsenic oxidation state, rather than total arsenic or total inorganic arsenic.

Key numbers

• LOD, linear range, and selectivity data in full paper.
• No food occurrence data.

Methods (brief)

Colorimetric detection of As(III)/As3+. Speciation-sensitive: specifically detects As(III) rather than total As. Water matrix validation only.

Implications

Certification: Method development; no food data. As(III) speciation relevant to understanding arsenic chemistry in food matrices. Courses: Demonstrates colorimetric approaches for arsenic sensing; note speciation-specific detection vs. total inorganic arsenic measurement.
