Exchange Behaviour

A new crystalline layered inorganic ion exchanger tin(IV) arsenophosphate with the formula Sn(HAsO4)(HPO4)•H2O has been prepared by refluxing the amorphous precursor. This exchanger has been characterized by X-ray powder pattern, chemical analysis, IR spectra, and thermal dehydration. Its ion exchange behaviour towards sodium ions is reported. The exchanger has an exchange capacity of 5.36 mequiv./g for Na+. The performance of tin(IV) arsenophosphate is compared with crystalline tin(IV) phosphate and arsenate. Keywords: cation exchanger, crystalline tin(IV) arsenophosphate, ion exchange, thermal behaviour, X-ray studies.
