摘要：

Tin(IV) antimonate with different Sb/Sn molar ratios has been prepared. The characterization of the product materials was carried out using X-ray diffraction pattern, themal analysis and infrared spectra. The saturation capacities of sodium and cesium were found to increase with Sb/Sn molar ratios. The K-d values on thermal treatment of tin(IV) antimonate, as a cation exchanger, have been measured for some heavy metal ions in the temperature range of 50-400 degrees C. The maximum adsorption of 10(-4)M of the metal ions studied was obtained at 400 degrees C. The selectivity sequence was Eu3+ > Co2+ > Sr2+ > Cs+ for the sample heated up to 400 degrees C. No adsorption was observed on the sample heated at 700 degrees C because of the formation of SnO2 and Sb6O13.
