doi:10.3969/j.issn.0253-2778.2020.07.001

Abstract

Abstract: For the shortcomings of traditional large-scale instruments in the aspect of real time in SITU detection and operability for detecting pollutant in water. A portable colorimetric nanosensor was constructed for the real time and in situ detection of As(III) in water. The nanosensor consisted of gold nanoparticles modified with trithiocyanuric acid (TMT-AuNPs), and its detection limit for As(III) reached 0.87 μg/L. It is believed that the colorimetric nanosensor will have wide application prospects in outdoor visual detection scenarios.

Key words: colorimetric nanosensor, visual detection, As(III)
