High sensitivity is obtained due to the use of the montmorillonites which displays outstanding capability in terms of adsorbing mercury ion due to its high specific surface and the presence of multiple binding sites. The experimental parameters and the effect of a chelating agent were optimized to further enhance sensitivity and selectivity. Linear calibration curves were obtained over the Hg(II) concentration range from 10 to 800μgL−1 for 5min accumulation, with a detection limit of 1μgL−1. Simultaneous determination of Hg(II) and Cu(II) was also studied, and no interference was observed. Figure Scheme for the Organic-inorganic pillared clay adsorbing mercury.
