title: [Study on melanin from taihe silky fowl and its complexes with Cu2+, Fe3+ ions by IR spectrum].
abstract: 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.
