FIELD: chemistry.
SUBSTANCE: method includes precipitation of one actinoid or co-precipitation of a larger number of actinoids in form of oxalate particles in fluidised bed by bringing in contact water solution, which contains actinoid or actinoids, with water solution of oxalic acid or oxalic acid salt and collection of oxalate particles.
EFFECT: obtaining actinoid oxalate in form of powders with high granulometric and morphological characteristics.
