... .. ... Create a 1:1 mixture of 65% nitric acid (HNO3) and 30% hydrogen peroxide (H2O2) to disperse Cerium (IV) Oxide particles and ensure stability in solution for at least an hour. When the CeO2nanoparticles are added to the HNO3-H2O2 mixture, the CeO2 should quickly dissolve in a matter of minutes. Monitor the dissolution process for completeness, ensuring that all particles are dissolved. Once dissolved, measure the UV absorbance to examine the Ce ion absorbance spectrum.
The question and answer is an example of how an incorrect process term can lead to errors. The question is: it is necessary to prepare a stable suspension of zirconium dioxide to obtain the UV spectrum of the dispersed system. However, ... .. ... makes a mistake and calls the formation of a dispersed system dissolution. Alvena Shahid recommends dissolving cerium dioxide in a mixture of nitric acid and hydrogen peroxide.
... .. ... needs to clarify that she wants to dissolve zirconium dioxide or prepare a dispersed system from it and in what medium.
Yuri Mirgorod The poster refers to cerium oxide not zirconium oxide so some typos in your reply. I agree, though, that the difference between dissolution and dispersion needs to be understood.
Thank you for highlighting the importance of clear scientific terminology Sir Yuri Mirgorod. I appreciate your perspective and recognize the need for precision, especially with complex processes like dispersion.
You're correct that my response focused on dissolution rather than dispersion of cerium oxide (CeO2. I apologize for any confusion my wording may have caused. To clarify, the goal was indeed to achieve a stable dispersion of cerium (IV) oxide particles.
It's crucial to distinguish between dissolution and dispersion processes, as they have different mechanisms and outcomes. In this case, the aim was to disperse cerium (IV) oxide particles for UV absorbance measurements.
