摘要: Abstract By introducing the amine group into phosphorus extractant, a novel aminophosphine compound bis(2-ethylhexyl) ((2-ethylhexylamino)methyl) phosphine oxide (DEHAPO, abbreviated as A) was synthesized for extraction of cerium (IV) (Ce(IV)) from sulfate medium (H2SO4). The influence factors including extractant concentration, H2SO4 concentration and temperature on Ce(IV) were investigated discussed. It is found that ability Ce(IV), thorium (Th(IV)) rare earths (REs(III)) (La, Gd, Yb) decreases in sulphate following order: Ce(IV) > Th(IV) > REs(III). process an exothermic reaction thermodynamic parameters calculated. extracted complex Ce(HSO4)2SO4·A loaded organic solution identified by slope methods further proved FT-IR spectral analysis. Stripping studies indicate can be effectively stripped phase. results separation (β) saturation loading capacity demonstrate DEHAPO could used to selectively extract with high efficiency good ability.
