| Abstract: | Seven new complexes of lanthanum sulphate with amino acids were synthesized in ethanol and aqueous solution. Chemical analysis, elemental analysis , infrared spectra and conductance measurements show that the complexes have the general formula of La_2 (AA)_n (SO_4)_3xH_2O (AA = Glycine,L-Alanine, L-Valine, L-Tyrosine , L-Glutamic aicd , L-Lysine and L-Arginine; n= 2, 4, 6; x=4 , 6 , 8). Infrared spectra indicate that the carboxyl groups and sulphate ions of complexes are coordinated. The thermogravimatric and differential thermal analysis studies show that the reactants underwent a series of decomposition stages, the endproducts were the oxide of lanthanum. The fluorescence spectra of complexes were investigated. |
