Mandelic acid and its derivative p-bromomandelic acid were found to be suitable precipitation reagents for triand tetravalent Pu/sup 4+/ions. Pu/+ is precipitated by both reagents from very weak acid solutions together with Yb carrier. Pu/sup 4+/ on the other hand is precipitated almost completely from strongly acid solutions with Zr carrier while Pu/sup 3+/ remains in solution. Under these conditions Pu/sup 6+/ is neither in neutral nor in acid solution taken down. This new reagent is so effective that certain valences of Pu can be separated from each other. Moreover it is possible to separate Pu/sup 4+/ from U in weakly acid solutions. The p-bromomandelic acid is superior to D, L-mandelic acid both in speed and completeness of precipitation. (T.R.H.)
