Direct and Derivative Spectrophotometric Method for Yttrium Determination in Different Rare Earth Concentrates

“…Two synthetic samples were prepared, the first, synthetic (1), was simulating the composition of rare earth monazite concentrate without Ce, which causes interfering effect either with conventional spectrophotometry or using the first derivative. The second, synthetic (2), constitutes only heavy rare earth elements with yttrium. Another two REE concentrate samples, sample (1), was prepared from monazite and sample (2) was prepared from xenotime.…”

“…The second, synthetic (2), constitutes only heavy rare earth elements with yttrium. Another two REE concentrate samples, sample (1), was prepared from monazite and sample (2) was prepared from xenotime. Both samples were measured using the advanced instrumental tool, inductively coupled plasma -optical emission spectroscopy (ICP-OES), and the data were gathered in Table (9).…”

“…Y-iron garnet is very effective microwave filter, Yaluminum garnet used as simulated diamond, Yttrium iron garnet is very efficient as an acoustic energy transmitter and transducer and cerium doped yttrium garnet crystals are used as phosphors to make white LED screens. (2) The growing importance of yttrium in the field of nuclear chemistry and metall-urgy necessitated the development of methods for the rapid determination of yttrium. (3) A variety of methods has been used for determination yttrium these include inductively coupled plasma atomic emission spectroscopy (ICP-AES) (4) , inductively coupled plasma mass spectroscopy (ICP-MS) (5-7) , flame atomic absorption spectrometry (FAAS) (8,9) graphite furnace atomic absorption spectrometry (10) , X-ray fluorescence (3) .…”
