Stability and distribution studies on Sn(IV) and Cr(III) arsenophosphates: Separations of metal ions.
The stability of tin(IV) and chromium(III) arsenophosphates in mineral acids and sodium hydroxide has been investigated. Structures for the two compounds are proposed, based on the results of thermogravimetric analysis, K(d) values for metal ions on these two compounds have been determined and separations of UO(2+)(2)-Th(4+), UO(2+)(2)-Zr(4+) and Na(+)-K(+) achieved.
