The authors study the reaction of uranyl salts with neutral organophosphorous compounds in aqueous solutions of mineral acids. They show that compounds of the R /SUB n/ P(O)-(OR) /SUB 3-n/ type (n = 0, 1, 2, 3; R = CH/sub 3/, C/sub 2/H/sub 5/) do not form complexes with UO/sub 2//sup 2 +/. In perchlorate solutions U/sub 2//sup 2 +/ forms complex with ((CH/sub 3/)/sub 2/ N)/sub 3/ PO. The equilibrium constant of this reaction is 6.4 + or - 0.6 mole/sup -1/. liter at 298 degrees K.
