Solid Phase Extraction of Inorganic Mercury Using 5-Phenylazo-8-hydroxyquinoline and Determination by Cold Vapor Atomic Fluorescence Spectroscopy in Natural Water Samples
Figure 7
Effect of eluent volume on the recovery of Hg(II) adsorbed on 5Ph8HQ by column method. Conditions: [Hg2+]: 2 ng mL−1, (50 mL), pH 4, and eluent: 5 M HCl + 5% CS (NH2)2/1 M HCl + 2% CS (NH2)2. Bars represent standard deviation for two replicates.
