Abstract
Hetero polyanions, namely, P2W17O6110-, P2W18O626- and SiW11O398- were extr acted by TBP/dodecane from HNO3 or I-ICI solution, as H10P2W17O61 in the ca se of P2W17O6110-. The distribution ratio of P2W17O6110- depended on both H + concentration and ionic strength of aqueous solution, and free-TBP concen tration in organic solution. Experimental equation was established for pred icting the distribution ratio of P2W17O6110- in nitrate system.
