The study aims to develop a rapid and selective sensing method for arsenate ions in water using silver nanoparticles.
Developed a sensing strategy using ninhydrin-functionalized silver nanoparticles (N-AgNPs) via chemical reduction under cold conditions.
Characterized N-AgNPs using spectroscopic and microscopic analyses.
Evaluated analytical performance in environmental water samples with recovery rates of 98-112% for As(V) ions.
Achieved a limit of detection (LOD) of 0.56 μM and a limit of quantification (LOQ) of 1.88 μM for As(V) ions.
Demonstrated high selectivity for As(V) ions compared to other metal ions in various tests.
Enabled rapid and economical determination of arsenate in environmental monitoring.
