Oxalic acid is added to an aqueous solution of zirconium oxynitrate and sodium nitrate with stirring and then phosphoric acid is added. The pH of the reaction mixture is adjusted to 3.5 with an aqueous sodium hydroxide solution and refluxed with heating for 78 hours. The precipitate is filtered, washed with water, dried and ground to obtain zirconium phosphate that is then immersed in an aqueous solution containing silver ion at a suitable concentration to obtain the compound represented by formula 1.
