英文摘要: Fluorescent powder plays an important role in the modern electronic lighting products. During the production of electronic lighting products, a large amount of waste fluorescent powder is generated. The major rare earth composition of this waste fluorescent powder is Europium (Eu) and Yttrium (Y), both being valuable resources worthy of the recycling process. To recover (Eu) and (Y) from the fluorescent powder, an integrated leaching method is adopted in this study. Leaching tests are performed and optimized with the use of various leaching reagents. Reagents such as HCl, HNO3, H2SO4, and NaOH are used along with the method of varying the leaching time and solid/liquid ratios at 27 and 70 °C. The result of leaching tests shows that the Eu and Y present in...
