Abstract
Inventia se refera la un procedeu de separare si purificare a ceriului în care, în scopul obtinerii unor randamente ridicate, de separare si purificare se separa din faza organica lantanidele coextra-se cu Ce la puterea 4+ prin spalare cu solutie de azotat de amoniu 25-100g/l la un raport faza organica: faza apoasa de 2:1 la circa 25 degree C, dupa care se extrage din faza organica azotatul de ceriu cu apa deionizata la 20-60 degree C.The invention relates to a process for the separation and purification of cerium in which, in order to obtain high yields, separation and purification, the lanthanides are coextracted with Ce at 4+ by washing with ammonium nitrate solution 25 -100g / l at an organic phase ratio: 2: 1 aqueous phase at about 25 degrees C, after which the cerium nitrate is extracted from the organic phase with deionized water at 20-60 degrees Celsius.
