Yttrium and other rare earth elements (REE) can be obtained from Xenotime minerals. Theses REEs are commercially needed in this industrial revolution (IR) 4.0 era to be used in many high-technology instruments such as microwave filters for radar, white LED lights, superconductors, fuel cells and radioactive isotopes to cure cancer. Thus, effort needs to eliminate impurities that may effect the materials characteristic and product efficiency. In the present work, pregnant leached solution (PSL) from xenotime minerals through alkaline fusion was precipitated with sodium bicarbonate (Na2CO3) and hydrogen peroxide (H2O2). This research was conducted with H2O2 volume in the precipitation process. The precipitates were characterized using X-ray fluorescence, field emission scanning electron microscopy and Raman spectroscopy analysis. Based on the results, it revealed that yttrium (Y) is likely to precipitate without existence of H2O2. Whereas dysprosium (Dy) and hafnium (Hf) precipitated at different H2O2 concentration. Meanwhile, praseodymium (Pr), terbium (Tb) and erbium (Er) remain in the filtrate with the existance of H2O2. [ABSTRACT FROM AUTHOR] |
