  • Title: Selective detection of hexachromium ions by localized surface plasmon resonance measurements using gold nanoparticles/chitosan composite interfaces.
    Author: Fahnestock KJ, Manesse M, McIlwee HA, Schauer CL, Boukherroub R, Szunerits S.
    Journal: Analyst; 2009 May; 134(5):881-6. PubMed ID: 19381379.
    Abstract:
    Selective removal of hexavalent chromium ions from aqueous solutions using a chitosan/gold nanoparticles composite film was demonstrated. Localized surface plasmon resonance (LSPR) was used to measure the interface stability and detect the incorporation of chromium ions over time. The effects of pH, ethylenediaminetetraacetic acid (EDTA), and various foreign ions such as trivalent chromium, sodium, calcium, phosphate, sulfate and chloride on the adsorption of hexavalent chromium were investigated.
