Six kinds of pyrophosphate were synthesized.The investigation on ion exchange properties showed that zireonyl molybopyrophosphate exhibited large exchange capacity and high distribution coefficient for cesium in the medium of 3 mol· L－ 1 HNO3.Preliminary study of its properties indicated that this material is a bifunctional inorganic ion exchanger with good thermal and chemical stabilities.ZMPP might be suitable for removing cesium directly from strong acidic HLLW.
