Nineteen elements including some from groups 2, 3, 4, 5, and transition elements were studied at constant 1 M HF and variable HCl concentration (0.1 to 11 M). The data are compared with adsorbabilities in HCl solutions, not containing HF. A large group of elements which are nonadsorbable from HCl solutions are also not adsorbed from HCl-HF mixtures. This group includes even such highly charged ions as Al(III), Y(III), Eu(III), Th(IV), and V(IV). Be(II) shows some adsorption at low HCl concentration in the presence of 1 M HF. The adsorption functions of many elements adsorbable from HCl solutions show little change on addition of HF. The adsorption functions may be substantially altered as shown for Sc(III), Ti(IV), Fe(III). Ga(III), Ge(IV), Sn(II) and (IV), and Sb(III) and (V). From the adsorption functions in HCl and HCl-HF, estimates of the extent of fluoride complexing are obtained. Application of the adsorption data to separations is discussed and illustrated with typical cases. (auth)
