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

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
