Embodiment 1
[0067] Use the treatment solution to treat the black powder of experimental group 1, the treatment solution is 20g of aqueous solution, add the black powder into the beaker containing the treatment solution, heat and stir at 50°C for 2min, after fully dissolving, filter while hot to remove the precipitate, and get Sample solution 1 is set aside.
Embodiment 2
[0069] Prepare the treatment liquid, add 1 g of hydrochloric acid solution with a concentration of 2% to the dispersion liquid 19 g of water, acidify the dispersion liquid, and finally add 0.002 g of crown ether 18-crown-6; use the prepared treatment liquid treatment number as experimental group 2 Add the black powder into the beaker filled with the treatment liquid, stir and shake for 5 minutes, fully dissolve, remove the precipitate after centrifugation, and obtain sample solution 2 for later use.
Embodiment 3~8
[0071] Examples 3-8 Refer to the preparation process of Examples 1 and 2 to prepare corresponding sample solutions 1-8 for future use. Among them, during the mixing process of the treatment liquid and the black powder, one or more methods of stirring, shaking, ultrasonication, and heating can be selected, and the process of slag removal can be selected by filtration or centrifugation, and those skilled in the art can choose to use it according to the actual situation. . Generally, sonication and heating can accelerate the dissolution.
[0072] The treatment liquid quality that embodiment 1~8 uses is 20g, but the component of each treatment liquid and content change to some extent, and concrete embodiment situation is as shown in table 1:
