In this paper, a novel bifunctional molecule dialkyl (2-(hydroxyamino)-2-oxoethyl) phosphonate (DAHAOEP) containing both phosphoryl and hydroxamic groups was designed and synthesized, and used as a uranium extractant. The extraction properties of DAHAOEP were focused. Dihexyl (2-(hydroxyamino)-2-oxoethyl) phosphonate (DHHAOEP) was shown to have a better extraction effect on uranyl ions than dibutyl (2-(hydroxyamino)-2-oxoethyl) phosphonate (DBHAOEP) and diethyl (2-(hydroxyamino)-2-oxoethyl) phosphonate (DEHAOEP). Under the optimal extraction co...
