Abstract:
meso-tetra(p-sulphonatophenyl)porphine reacts with several metal ions in ammoniacal aqueous solution. The resulting complexes are extractable into methyl isobutyl ketone with tricaprylmethylammonium chloride. The distribution ratios for the metal ions range from 8 for Mn(II) to about 1400 for Cd(II), corresponding, respectively, to single-stage extractions of 33-99% with a phase-volume ratio V (w)V (o) = 18. A procedure has been developed for the multielement preconcentration of several trace metals (Mn, Co, Ni, Cu, Cd, Pb) from sea-water and their subsequent determination by graphite-furnace AAS.
