Abstract
Spectrophotometric and potentiometric investigations have been carried out on copper-diethanolamine system. Job plots at 900, 900 and 580 mμ have indicated the formation of CuD++, CuD2 ++ and CuD3 ++. Then- pA curves obtained indicate the formation of CuD++, CuD2 ++, CuD3 ++, CuDOH+, CuD2OH+ and CuD3OH+. Then- pA curves have been analyzed to obtain the stability constants of these complexes. Absorption curves of pure complexes have been computed by a graphical method. Gaussian analysis of the absorption curves of pure and hydroxy complexes show the presence of a second band, indicating that the structure is that of a distorted octahedron.
