Title:

PHOSPHOROUS DENDRIMERS, PREPARATION METHOD THEREOF AND USE OF SAME FOR THE EXTRACTION OF ACTINIDES AND LANTHANIDES

Document Type and Number:

WIPO Patent Application WO2004076509

Kind Code:

A3

Abstract:

The invention relates to novel phosphorous dendrimers comprising a core, at least one generation and an outer layer consisting wholly or partly of identical or different motifs, said motifs having formula (I), wherein: R1 and R2, which can be identical or different, represent alkyl, alkoxy or aryl groups. Said dendrimers can be used to extract actinides and lanthanides from aqueous solutions containing same.
