Abstract
The distribution of titanium, chromium and cadmium between phosphoric acid solutions and solutions of p-(1,1,3,3-tetramethyl butyl) phenyl p hosphoric acid in kerosene diluent was investigated under various cond itions. The aqueous and organic phases were analyzed by inductively co upled emission atomic spectrophotometry. It was found that the extract ion order of p-(1,1,3,3-tetramethyl butyl) phenyl phosphoric acid for metals was Ti > Cr > Cd for concentrations of H3PO4 greater than or eq ual to 7 M and Cr > Cd > Ti for concentrations of H3PO4 less than or e qual to 5 M.
