[Study on melanin from taihe silky fowl and its complexes with Cu2+, Fe3+ ions by IR spectrum].
OBJECTIVE
The interaction between Cu2+, Fe3+ and Melanin from Taihe Silky fowl for different pH values was investigated in heterogeneous system.


METHODS
The IR spectrum of melanin and its complexes with Cu2+, Fe3+ ions was determined.


RESULTS
The carbonyl group of melanin may interact with metals.


CONCLUSIONS
Taihe Silky fowl melanin is the mixture of pheomelanin and isomelanin.
