Abstract

A selective, simple and low-cost method for the Colorimetric determination of Fe3+ ions based on Chitosan capped silver nanoparticles (Chit-AgNPs) is presented. Chitosan is a cationic polyelectrolyte possessing amino and hydroxy groups which make it widely used as a capping agent for Ag NPs. The synthesized Chitosan capped silver nanoparticles with excellent colloidal stability were characterized by UV-Vis spectrometry, transmission electron microscopy, Fourier transform infrared, and X-ray diffraction. Chit-AgNPs exhibit a strong surface plasmon resonance band which disappears in the presence of increasing concentrations of Fe3+ ions. This system showed a visually detectable color change from brownish-yellow to colorless for the selective determination of Fe3+. The method can be applied for the determination of Fe3+ ions in the concentration range of 1. 0 × 10-6-5. 0 × 10-4 M. The detection limit was determined from three times the standard deviation of the blank signal (3σ /slope) as 5. 3 × 10-7 M. The developed method was successfully applied for the determination of Fe3+in real samples.
