title: Analytical applications of organic reagents in hydrophobic gel media-II Selective preconcentration of mercury(II) with dithizone or thiothenoyltrifluoroacetone gel.
abstract: Mercury(II) at the sub-ppm level is selectively trapped on a column packed with cross-linked polystyrene gel beads soaked with zinc dithizonate or thiothenoyltrifluoroacetone. Mercury trapped on the beads can be back-extracted into the aqueous phase with a hydrogen halide solution. Mercury in sea water at ppm or ppM level has been successfully preconcentrated by this procedure.
