The solubility of sexa- and tetravalent uranium, zirconium, and thorium phenylarsonates in solutions of different acidity, in the presence of phenylarsonic acid, was studied by the labeled atom method. The conditions for their most complete precipitation were established and the solubility was determined as follows: uranium(IV) phenylarsonate 3 x 10/sup -5/ M; uranium(IV) phenylarsonate 1 x 10/sup -5/ M; zirconium phenylarsonate (0.5 plus or minus 0.2) x 10/sup -5/ M; and thorium phenylarsonate 10/sup -5/ M. The logarithms of the concentration constants for the reactions of phenylarsonate formation were calculated to be equal: uranium(VI) 2.2 plus or minus 0.2; uranium(IV) 6.5 + 0.3; zirconium 11.5 plus or minus 0.3; and thorium
