Abstract
The synergic extraction of Am(III) by thenoyltrifluoroacetone (HTTA) a nd triphenylarsine oxide (Ph3AsO) in chloroform from perchlorate mediu m has been investigated. The effects of the different parameters affec ting the extraction were studied and the stoichiometry of the extracte d species was found to be Am(OH)(TTA)2Ph3AsO. The kinetics of this ext raction has been studied using a stirred Lewis cell at ionic strength 0.1 (NaClO4). The effects of rate of stirring, concentration of HTTA, Ph3AsO and H+ as well as temperature on the rate of extraction were st udied.
