Present paper describes a new method for synthesis of tin(IV) iodotungstosilicate (TITS) exchanger. Ion exchange capacity (IEC) of the exchanger is found to be 0.86 meq/g for Na+, possesses good stability against high temperature upto 600 degrees C and chemicals of different strengths. IEC is determined for different metal ions, distribution studies are done and K-d values are calculated. The exchanger is selective for lead ions as shown by K-d value (176.78). IR of the compound indicates all the four expected components. XRD and SEM show that exchanger is in amorphous form. The synthesized material is useful in separation, water softening and water decontamination.
