Abstract:A rapid and selective colorimetric detection of Ni2+ was developed using silver nanoparticles (AgNPs) with β-cyclodextrin (β-CDs) as reducing and stabilizing agents. Characterization was assessed by spectrophotometer UV-vis, Fourier transform infra-red (FTIR), transmission electron microscopy (TEM), and particle size analyzer (PSA). The AgNPs-β-CDs were relatively stable after being stored for 5 months. The addition of Ni2+ to the AgNPs-β-CDs shifted the surface plasmon resonance (SPR) band at 409 nm. Synthesi… Show more
