Sectrophotometrical evaluation of the stability of melanine complex with Cu (II) ion
Keywords:
Melanin, Melanin-Cu(II) complex, UV spectrometer, stability constant, molar absorption coefficient
Abstract
The complex of melanin with Cu (II) ions was synthesized, and the stability constant and molar absorption coefficient of this complex were evaluated by UV-spectroscopic method by the isomolar series method.
