Abstract: | The reactions that occur during the mechanochemical treatment of europium nitrate with 1,10-phenanthroline were studied by X-ray electron, infrared, and luminescent spectroscopy. Two minutes of mechanical activation resulted in the formation of europium nitrate, 1,10-phenanthroline, and water. According to the X-ray electron spectroscopy data, the coordination of 1,10-phenanthroline to europium nitrate was accompanied by a decrease in the Eu 4d 5/2 binding energy. Intense mechanochemical transformations caused changes in the composition of the surface of samples. Changes in the shape and size of reaction mixture particles and the morphology of sample surfaces after mechanical treatment in a ball mill compared with the initial mixture were studied. |
