Description
The complex formation of Np(IV) and Pu(IV) with sulphate ions was studied in perchloric -sulphuric acid soluotions at an ionic strength of 2.0 and STAH/sup +/! = 2.0 M by the distribution method employing the liquid cation exchanger dinonylnaphthalenesulphonic acid. Similar sotudies on Np(IV) were done using TTA extraction method also. The enthalpy and entropy changes associated wioth the complex formation were deotermined from the temperature variation of the formation constants. A comparison of the thermodynamic data for the sulphate complexing of all the oteotravalent actinides was made. (GE)
