Abstract EN
8-Hydroxyquinoline (8-HQ) was chosen as a powerful ligand for Hg solid phase extraction.
Among several chelating resins based on 8-HQ, 5-phenylazo-8-hydroxyquinoline (5Ph8HQ) is used for mercury extraction in which the adsorption dynamics were fully studied.
It has been shown that Hg(II) is totally absorbed by 5Ph8HQ within the first 30 minutes of contact time with t1/2 5 minutes, following Langmuir adsorption model.
At pH 4, the affinity of mercury is unchallenged by other metals except, for Cu(II), which have shown higher Kd value.
With these latter characteristics, 5Ph8HQ was examined for the preconcentration of trace levels of Hg(II).
The developed method showed quantitative recoveries of Hg(II) with LOD = 0.21 pg mL−1 and RSD = 3–6% using cold vapor atomic fluorescence spectroscopy (CV-AFS) with a preconcentration factor greater than 250.
