Synthesis, characterization, and ion exchange behavior of antimony(V) phosphate: selective adsorption of cadmium and...

Antimony(V) phosphate has been prepared as a new inorganic ion exchanger suitable for the selective adsorption of cadmium and mercury, the two chief polluting metals. The materials possesses good ion exchange capacity and stability, both thermal and chemical. It has also been characterized and an empirical formula has been proposed on the basis of its chemical analysis and certain instrumental studies like infrared spectroscopy, X-rays, thermogravimetry, derivative thermogravimetry, differential thermal analysis, and pH titrations.
