Preparation and characterization of dialdehyde starch and its` cross-linking with copper (II) ion

Author(s): AA Salisu, H Musa, H Abba and AA Kogo

Starch derivatives were prepared using potassium periodate as oxidizing agent under mild condition and successfully reacted with copper(II) ion resulting in cross-linking of the dialdehyde part of the modified starch. The carbonyl content was determined and the starch, dialdehyde starch and the polymer copper II complex were characterized by conductivity test, solubility test, melting point, viscosity measurement and FT-IR spectral analysis.
