ABSTRACT
Novel polydentate neutral organophosphorus ligands containing two diphenyl-(diethylcarbamoyl-methyl)phosphine oxide moieties fixed on the arene platform via methylene-1,2,3-triazole linkers (Ar-CMPO) were synthesized by the method of click chemistry and studied as an extractant for Pd(II), U(VI), Th(IV), and lanthanides(III) ions from HNO3 solutions.
