Synthetic porphyrins have, in the last years, gained increasing interest in analytical chemistry as unique reagents for the detection of metal ions. The porphyrin is a high sensitive chromogenic reagent. Porphyrins and their metal complexes generally exhibit characteristic sharp and intensive absorption bands in visible region. The region from 400 to 500 nm, which is called the Soret band, shows the most intensive absorption, and molar absorptivities about 10⁵ are often found. Soret band (400-500 nm) shows the most intensive absorption of these compounds, molar absorptivities often being about 10⁵. The Soret band is widely used for spectro- photometric detection of metalloporphyrins. From the perspective of analytical chemistry, the porphyrin ligand has turned out to be very versatile, and almost all metals have been combined with porphyrin. From this point of view several porphyrins become useful as the spectrophotometric reagents for the determination of metal ions.
