    Malachite green dye adsorption from aqueous solution using silver nanoparticle (AgNP) stabilized with sodium tripolyphosphate cross-linked chitosan is reported in this study. Silver nanoparticle prepared was characterized by Fourier Transform Infra-Red Spectroscopy (FTIR), X-ray diffractometry (XRD), UV-visible spectrophotometer and Scanning Electron Microscopy (SEM). The crystalline nature of the AgNP was revealed with XRD. The cubic face-centered structure of the synthesized silver nanoparticle was confirmed. This was supported by the observed sharp four diffraction peaks with peaks intense appeared at 2θ=38.09°, 44.15°, 64.67°, and 77.54°. However, the SEM micrograph of the synthesized AgNP revealed the spherical shape of AgNP with a non-uniform granular shape attributed to bio-mediated ionic gelation process. The surface of the synthesized AgNP has a spherica.. Read More»
