10. KOH, which was used for making complex, contained sodium as impurity and its concentration was determined by AAS. Therefore, the concentrations of sodium ion as reference were made with those amounts in KOH and the addition of Aldrich calibration standard solution.
11. 3- is the complex of dysprosium trichloride with triethylenetetraaminehexaacetic acid. The concentration of shift reagent changes the chemical shift of sodium.
