摘要：

Extraction with di-o-tolyl phosphoric acid (HDTP, HA)-benzene-20% hexan-1-ol system was studied as function of contact time, concentrations of extractant in the organic phase and H//2SO//4 in the aqueous phase, and temperature. The order of extractability is: Ti(IV) greater than Fe(III) VM GT TH Fe(II). Separation of Ti(IV) from iron seems promising if iron is present in the divalent state. Mechanisms are discussed.
