摘要：
A new inorganic ion-exchanger: iron(III) tungstophosphate was synthesized and characterized by IR spectrophotometry, TG analysis and pH-titration. Distribution coefficients of several metal ions in dilute HNO3 and NaNO3 were measured and possibility of achieving column separation of several binary and ternary mixtures was demonstrated. The exchanger was found useful for preconcentration of Hg(II) ions from dilute aqueous solutions.
