Abstract

Given that gold nanoparticle has been taken into consideration in the past few years and it has been widely used as a sensor, the synthesis of gold nanoparticle with specific groups on its surface is of great importance. Therefore, the available and straightforward method was synthesis with 1-1-hydroxy naphthyl-6-nitro-2-naphthol-4-sulfonate (HNS) as a capping and reduction agent for a gold nanoparticle. The structure of HNS-gold nanoparticle was characterized by surface plasmon resonance (SPR) peak around 525 nm, TEM, TGA, FT-IR spectroscopy, Dynamic light scattering (DLS) and the size of the nanoparticles with transmission electron microscopy (TEM) was observed to 25-35 nm. For sensing of chromium (III) ions, the surface plasmon resonance (SPR) peak shift was used and it is linearly related to the concentration of Cr(III) ions in the 50-500 nM, the LOD was found to be 20 nM. © 2019 Desalination Publications.
