Abstract
Zirconium tungstate (ZW) an inorganic itha exchanger of the class of tetravalent metal acid salt has been synthesized and characterised for elemental analysis, spectral analysis and thermal analysis. Its chemical stability has been assessed in various acidic, basic and organic media. Ion exchange capacity of ZW has been determined and its application in waste water treatment has been explored. ZW has been found to be a promising material in softening of water and in the removal of heavy metal ions such as mercury, lead, nickel and silver.
