ABSTRACT This review covers the application of porphyrins for preconcentration and determination of metal ions. They can be used for modification of sorbents in solid phase extraction, as sensitive spectrophotometric reagents for the determination of metal ions and derivatizing agents in capillary electrophoresis. 5,10,15,20-tetrakis (4- carboxyphenyl) porphyrin (TCPP) serves as an example of porphyrin ligand for the presentation of the above mentioned applications.
