A new method for separation and preconcentration of trace amounts of Cu(II), Ni(II), Pb(II), Cd(II) and Mn(II) ions in various matrices was proposed. The method is based on the adsorption and chelation of the metal ions on a column containing

We describe a new autoradiographic technique for differentially demonstrating the presence of trace amounts of cadmium that remains unbound to metallothionein in tissue sections. This procedure involves [14C-1,4,5,8-naphthol]-1-(2-thiazolylazo)-2-naphthol (TAN) instead of a metal radioisotope. Tissue sections were stained using labeled

Cloud point extraction has been used for the preconcentration of manganese, after the formation of a complex with 1-(2-thiazolylazo)-2-naphthol (TAN), and later analysis by flame atomic absorption spectrometry using octylphenoxypolyethoxyethanol (Triton X-114) as surfactant. The chemical variables affecting the separation
