Abstract

    It was confirmed in this research that the ligand calcichrome formed stable complex with calcium ion at pH of  8.5 which verified by UV/Vis and FTIR spectral analysis and the complexation occurred via hydroxyl groups .


The stoichiometric ratio of the formed complex was found to be 1:1 by mole ratio and continuous variation methods . Dry ashing method of the complex and flame emission photometric analysis offered a calcium percentage in calcium complex equal 4.5% with an error of 2.41% due to experimental errors .
