| Abstract: | The dimethylformamide(DMF)residue was incinerated into ash and then dissolved in HCl solution.Concentration of five cations in the solution were determined by iron chromatography and converted into elemental content in the residue.The DMF residue contains 4.636% sodium,0.849%potassium,2.083% calcium and 1.54% magnesium.Iron was not detected.It is found that the accuracy is greatly influenced by incineration temperature. |
